How to Earn 10 Billion Won: 1-Year Goal and Business Growth
David Adelman's case does not prove that an individual can earn 10 billion won in a year. It explains how operational results built through hands-on work lead to investment and the conditions that determine individual compensation.
Advice on earning the first $1 million is not proof that 10 billion won was earned in a year.
A business's revenue and assets under management are not the same as an individual's income or net worth.
Operational results achieved in an existing business provide a basis for raising investment and negotiating compensation.
For those results to translate into personal income, the compensation criteria and payment terms must be agreed upon.
Even if a business grows through investment and loans, the risk of losses and responsibility for operations remain.
There is no verified, generally applicable way to build a personal net worth of 10 billion won within a year. Adelman’s story is about growing a business and raising capital through operational results. The key lessons to apply are learning on the job, demonstrating results, and agreeing on compensation terms.
The amounts in this case are based on a BigDeal interview published on August 24, 2026.
Is this a case of earning 10 billion won within a year?
The interview does not establish that David Adelman personally earned 10 billion won in one year. The question put to him was how to make his first $1 million. His answer was to learn from an existing business and increase its value.
The first $1 million and 10 billion won are different amounts. Income earned over a specific period must also be distinguished from accumulated wealth. Before setting a goal, decide what you want to reach 10 billion won.
Type of goal | Meaning | Records to check
Annual revenue of 10 billion won | Amount a business sold in one year | Revenue records for that period
Annual net profit of 10 billion won | Final profit after deducting costs and other expenses from business revenue | Income statement for that period
Personal net worth of 10 billion won | Personal assets minus liabilities | Asset and liability records as of the same date
Equity valuation of 10 billion won | Value assigned to an ownership stake | Basis for the valuation and equity rights
Personal cash receipts of 10 billion won | Amount actually received by an individual | Payment and deposit records and tax treatment documents
Net worth is calculated by subtracting liabilities from assets. The U.S. Securities and Exchange Commission’s Investor.gov guide to assessing your finances also explains this measure. An increase in net worth does not mean an equal amount of cash has become available.
What can be verified about David Adelman’s business
Adelman is an operator who grew a student housing business. His business history appears in his Campus Apartments profile. The assets under management described by the company are not Adelman’s personal wealth.
The company says he joined the business by investing $2,000. His answer about having no capital or connections is therefore hypothetical advice. His actual starting point should be distinguished from the choices he says he would make if starting over. His business history is described in Campus Apartments’ David Adelman profile.
The BigDeal interview discusses an institutional investment deal in 2006. Adelman says he raised $300 million at the time. He then describes a $1 billion deal that used debt. This is his recollection, not a statement of personal income.
Amount in the interview | What it describes | Important distinction
$1 million | A question about how to make a first substantial sum | Not a deadline or a record of actual earnings
$300 million in 2006 | Capital raised for an institutional investment deal | Not money he personally earned and held
$1 billion | Size of a real estate deal using equity capital and debt | Not personal net worth or profit from a sale
The context for these amounts can be checked in the BigDeal interview transcript. Converting them to won would require an exchange rate and a reference date. This article keeps the amounts in the dollars used in his account.
Calculation example: The difference between capital raised and deal size
The calculation in the interview shows how borrowing increases the size of a deal. Adelman uses an example of 30% equity capital and 70% debt. This ratio is not a lending term that applies to every real estate deal.
· Deal size: $300 million ÷ 30% = $1 billion
· Equity capital: $1 billion × 30% = $300 million
· Debt: $1 billion × 70% = $700 million
Here, equity capital is money contributed to the business. It does not mean that Adelman personally provided all of it. His personal share cannot be calculated without knowing his ownership stake and distribution terms, among other things. Deal size alone cannot tell us how much he earned personally.
How to learn from an existing business when you have little capital
Adelman advises building operational skills in an existing business. He gives examples of industries with established demand, such as heating and cooling and plumbing. His point is to find a role in bringing in more customers or reducing costs.
To apply this advice, first identify work you can learn to do. Look at both how the business generates revenue and where it incurs costs. The following steps are a practical checklist drawn from this case.
· Find out why customers pay. Determine whether the demand is recurring.
· Choose an improvement you can take responsibility for. Start with work you have the authority to handle, such as customer service or job scheduling.
· Record the starting point. Keep the comparison period and calculation method with it.
· Check the results. Distinguish changes in revenue from additional costs.
· Negotiate compensation based on verified results. Put the payment terms in writing.
You can understand the business as a whole while working as an employee. Taking on more responsibility, however, does not automatically give you an ownership stake. It is better to agree on your authority and performance measures first.
The opportunity Adelman found in student housing and the work of operating it
Adelman focused on recurring demand for student housing. He says he paid attention to cases in which parents covered the rent. Improved cash flow from existing buildings also helped him persuade investors.
His account should not be treated as a set of investment conditions that applies near every university. Student numbers and housing supply must be checked for each area. The fact that someone is paying the rent does not guarantee a profit.
Opportunity seen in the case | Conditions to check in an actual business
Housing demand from incoming students | Student numbers at the university and patterns of commuting and residence
Parents’ support with rent | How rent is actually paid and how late payments are managed
Better operation of existing buildings | Repair costs and property management staffing costs
Expansion into other areas | On-site managers and service quality control
Student housing is an operating business that requires responding to residents. Maintenance, repairs, and rental management continue after a building is acquired. Adelman emphasizes managing people and the organization when expanding into other areas.
Comparing starting a business, participating in one as an employee, and investing
The skills and risks involved differ according to how income is generated. No path guarantees reaching 10 billion won within a year. Compare them based on your current experience and the responsibilities you can take on.
Path | How income or assets grow | Conditions to check first
Improving a business as an employee | Salary, performance bonuses, or agreed equity compensation | Performance measures and compensation rights
Starting a new business | Business profits and an increase in the value of an ownership stake | Customer demand and operating funds
Acquiring an existing business | Profits and an increase in the value of the acquired business | Debt, contracts, and actual cash flow
Selling an ownership stake | Receiving payment for a stake you own | Buyer, payment terms, and sale terms
Investing in stocks or crypto assets | Price increases, dividends, or other returns | Potential losses and transaction structure
Recognizing a growing industry and realizing a return are different skills. Technical expertise does not replace acquiring customers or selling an ownership stake. Business investors must also consider their responsibility for direct operations, in addition to price fluctuations.
Investing with borrowed money can magnify losses. With securities margin trading, losses can exceed the amount invested. This risk is described in Investor.gov’s investor alert on short-term trading.
The terms needed to turn results into personal compensation
For business results to become personal income, a compensation agreement is needed. An increase in company profits is separate from an increase in an employee’s assets. Even if you receive equity, you may not be able to turn it into cash right away.
This distinction creates another task when putting Adelman’s advice into practice. You need to decide both how you will contribute to the business and how you will be paid. The following items provide a basis for reviewing what has been agreed.
Form of compensation | Items to check
Performance bonus | How performance is measured and when payment is made
Profit sharing | Which profits are shared and which costs are deducted
Equity compensation | Conditions for acquiring equity and how additional investment changes ownership percentages
Sale of equity | Conditions for selling and the payment schedule
Costs may also rise as revenue grows. It would therefore be inaccurate to count the entire increase in revenue as your personal contribution. Check that the performance records and compensation agreement use the same measures.
Records that demonstrate trust and the flow of money
Explaining trust requires records that let others verify results. The trust Adelman describes is closer to a history of repeatedly keeping promises. It should not be interpreted as a return that grows at a steady rate like interest on a deposit.
Records of business results and records of the source of funds serve different purposes. The former show what was improved. The latter explain where money came from and how it was used.
Record | What it helps verify
Operational records from before and after an improvement | Changes measured on the same basis
Revenue, cost, and deposit records | The connection between results in the books and actual cash
Investment and loan agreements | The nature of money received and repayment or distribution terms
Equity and compensation agreements | Rights belonging to the individual
Equity sale and payment receipt records | The difference between a valuation and the amount realized
Keep other people’s investment funds separate from personal living expenses. If you receive proceeds from a sale, keep the contract and deposit records together. Check tax and reporting obligations with the tax authority that has jurisdiction where you live.
Terms to check beyond price in a negotiation
Adelman advises looking at deal terms as well as price. The timing of payments and who bears the risk can change the outcome of a deal. He says he writes down the terms he is willing to accept before negotiating.
Negotiation item | Basis for assessment
Price | Expected return and losses you can bear
Payment timing | Cash needed when payment is due
Contract period | How long responsibilities and costs continue
Risk allocation | Who bears the burden if problems arise
Ongoing relationship | Whether the other party keeps promises and discloses information
He also describes missing out on a building deal he needed because of his emotions. His advice is to distinguish rude behavior from the economics of a deal. It does not mean accepting signs of fraud or contractual risks.
Common mistakes when reading success stories
It is easy to read the size of a business and a person’s wealth as the same number. Focusing only on a successful person’s results can also obscure their starting conditions. These distinctions help you read success stories more accurately.
· Mistaking capital raised for earnings: Investment funds come with distribution terms.
· Mistaking a loan for an increase in wealth: Borrowed money must be repaid.
· Mistaking a valuation for cash: Before a sale, it is not sale proceeds.
· Mistaking a success story for the probability of success: One case cannot establish a probability.
· Mistaking long hours for a formula for earnings: Time worked alone does not determine compensation.
Adelman also talks about explaining his business goals to his family. He says he had family members gain experience elsewhere before working with him. Teaching them about saving, investing, and giving is also part of his approach to family education.
These choices are his personal operating principles. They are not required qualifications for starting a business or universal standards for working hours. Before applying them, consider both living expenses and the time needed to care for family.
What to check when setting a one-year goal
Set a one-year goal that distinguishes the amount you want from the results you can verify. Adelman’s case shows the connection between learning on the job and achieving small results. The conditions under which each step leads to personal income must be checked separately.
· Define the type of goal. Write down whether you mean revenue, personal income, or net worth.
· Record your starting position. List your current assets and liabilities as of the same date.
· Choose work to improve. Identify the records you will use to check the results.
· Agree on compensation and responsibilities. Put payment terms and the scope of your obligations in writing.
· Decide whether to expand. Check whether the results can be repeated and what funding is needed.
