Bill Gates conducts two "Think Weeks" every year.

A person runs to a small cabin in the suburbs, cuts off all contact with the outside world, and does one thing - deep thinking.

Elon Musk once said: "Don't chase money, chase valuable skills. When you have valuable skills, money will chase you."

Ability is the true wealth.

Money earned by luck can be lost due to a lack of skills. Only money earned through ability can be sustained. It's like playing a game; what really matters is not the gold coins, but your level, skills, and equipment. Gold coins can be spent, but abilities will always be with you.

Warren Buffett said when talking about investing in oneself: "The best investment is in yourself. No one can take away your abilities, and no one can tax them." Abilities are your lifelong moat. When you have the ability to make money, no matter how the external environment changes, you can make a comeback.
