Success is measured not just in profits, but in positive impact.

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

知道我们所知道的，知道我们所不知道的，这才是真正的知识。

Grief is love turned into an eternal missing.

Positive psychology is not just about feeling good, it's about the good life.

我不喜欢在任何事情上失败，但我最大的成长不是来自胜利，而是挫折。
