Mobility makes people progress, and pride makes people fall behind. We should always remember this truth. ——Mao Zedong Once we have achievements, we cannot be like a ball that cannot be hit by others. It can jump as high as a light tap. The greater your achievements, the more modest and cautious you must be. ——Wang Jinxi I have some doubts about the word "proud". Anyone who has a little bit of drive and ability always believes in himself and is a person with some opinions. The more assertive a person is, the more confident he is. This one isn't bad.
