What are the three obvious "characteristics" of a thoughtful person?

The characteristics of people with many minds are: 1. Talking deliberately to please others is like flattering others. He won't fully believe what others have done, and he won't show it. I can keep things in my heart, and there are many things that are beneficial to my development that I won't tell others. On the contrary, people who have no mind's eye are more likely to trust others and publicize what they know.
