It is enough for a person to do only these three major things in his life, and the rest are trivial things.

1. Study how to make money. Remember, making money is your lifelong major event, because it can solve more than 99% of the problems.

2. Study human nature. We deal with people every day. If you can see through human nature, you will be halfway to success.

3. Respect your body. Only with a healthy body can you have the strength and resources to make a living.
