A Word of Advice from Lao Tzu

A good advice from Lao Tzu:

When Confucius was about thirty-three or thirty-four years old, he went to Chou, the Emperor’s capital, to study the ancient rites and ceremonies and visit Lao Tzu who was famous in Taoism. When Confucius was going back to Lu, Lao Tzu gave him some advice as a goodbye gift: "I have heard that rich people give people money and kind people give people advice, and so I am going to give you some advice: A man who is intelligent and thoughtful is often in danger because he likes to criticize people. A man who is well-learned and good at arguments often endangers himself because he likes to reveal people’s flaws. Don’t do that even if you are a son or a minister at court."
