人生成功的公式其实很简单

Is success in life really so difficult? In fact, success can be expressed through a few simple formulas that make its sources and paths easier to see. These formulas come from Naval's ideas. Simple yet profound, they are worth reflecting on and learning from.

1. Happiness = Health + Wealth + Good Relationships

Health is the foundation, including both physical and mental well-being. Simply having a healthy body and mind already gives us much to be happy about.

Wealth gives us more choice and freedom. It lets us go where we want and do what we want, but it is a tool rather than an end and should not be pursued excessively or treated as the ultimate goal.

Human beings are social creatures who need to be understood and supported. The quality of our relationships matters more than their number.

2. Health = Exercise + Diet + Sleep

I would add mindset and emotion. Whether we remain optimistic, calm, and emotionally steady has a profound effect on health. We need to care for both body and mind.

3. Exercise = High-Intensity Endurance Training + Sports + Rest

Naval mentions sports here but separately includes high-intensity endurance training. I believe he is emphasizing the distinctive benefits that sustained, high-energy exercise brings to cardiovascular fitness and endurance.

4. Diet = Natural Foods + Intermittent Fasting + Plants

Eat fewer processed foods. Eat more plants, which are rich in fiber, vitamins, and antioxidants.

Intermittent fasting can activate “autophagy,” helping the body clear out damaged cells, and may offer other benefits such as weight loss. There are several forms of fasting. One common approach is to skip breakfast and eat only lunch and dinner, creating a sixteen-hour fasting window and an eight-hour eating window. Fasting is not right for everyone, however; someone with a low body-fat percentage like me may not be well suited to it.

5. Sleep = No Alarm Clock + 8–9 Hours + Circadian Rhythm

Our sleep consists of a series of cycles. Waking naturally allows a cycle to finish, while an alarm can interrupt it.

Getting enough sleep is certainly beneficial, although the amount each person needs differs. Eight to nine hours is a common range.

**6. Wealth = Income + Wealth \* Investment Return**

Your earnings from work are active income, while returns on wealth are passive income: your assets continue to grow without requiring more of your time. Some returns carry risk, such as those from funds and stocks; others may be more stable, such as rent and book royalties.

7. Income = Accountability + Leverage + Specific Knowledge

In the workplace, greater responsibility generally brings higher income. Entrepreneurs bear the greatest responsibility because they are accountable for the operation and development of an entire company.

Leverage means using resources to amplify output. A company may raise capital to expand, use technology to reduce repetitive work, or draw on the power of a team to achieve a goal. Managers, for example, operate with high leverage.

Specific knowledge is the distinctive combination of ability, experience, and understanding that you possess. The stronger it is, the more capable and difficult to replace you become—and the greater your potential income.

8. Investment Return = Buy and Hold + Valuation + Margin of Safety

Choose high-quality assets, buy them, and hold them for the long term. Do not fixate on short-term fluctuations or trade too often. I once wrote an article titled “As Long as You Stay at the Table, You Haven't Lost.” Investments always fluctuate; where there is a fall, there can also be a rise. Be patient.

Assess an asset's valuation—in other words, decide whether it is worth the price. Choose assets that are undervalued or reasonably valued and still have room to grow. This gives you a wider margin of safety.
