In this lifetime, one only needs to do three major things.
The first thing is to study how to make money; money can solve 90% of life's problems, and the remaining 10% can be alleviated with money.
The second thing is to study human nature; as long as you see through human nature, you can remain undefeated in the trading system.
The third thing is to take care of your body; do not exchange health for material possessions.
