My personal suggestion: You must practice your temperament through small bets.
99% of the wealth in this world comes from high risks. The essence of key decisions is gambling. If you cannot accept gambling, you can only earn hard money without leverage.
100% certain things are the money you earn by trading your time, such as being a bottom-level farmer or being a low-level employee.
In the process of gambling, learn to manage risks and cultivate a calm mind.
The biggest risk is not daring to take any risks. Taking risks is an essential path in a high-level life.
