Personality changes more during your 20s than at any other time in life.

生活是一首歌，唱出来吧。

Positive emotions are not trivial luxuries, but instead may be critical necessities for optimal functioning.

The best policies are those that last longer than a political term.

成功绝非偶然。它是努力、坚持、学习、牺牲，最重要的是热爱你所做的事情。

Every failed experiment is a step closer to success, as long as you learn from it.
