Three common mistakes people make in life:
1. Speaking clearly to those who cannot understand.
2. Undertaking serious tasks with unreliable people.
3. Seeking emotional bonds with those who are heartless.
In life, keep a scale in your heart. Choose the right people and the right ways.
Speak to the wise, work with the steady, and share your heart with the sincere.
Better to argue with a wise person than to talk to a fool.
Spend your time and affection on those who deserve them — that is where meaning lies.
