Don't be too clever.

1. If you want to be happy, you can't be too smart or too stupid. This state between cleverness and stupidity is called wisdom.

Feeling: Too smart makes people hard to prevent, too stupid makes people fiddle, and it's hard to be confused.

2. Let go if you don't want to love, shut up if you don't want to say, and let go if you don't want to hate.

Feeling: Everything will pass, don't be too persistent.

All negative emotions and mentality have no effect on people and things you are dissatisfied with, but they have great effect on yourself and your relatives and friends.
