The best way to make people happy is to make them laugh.

每个人都害怕受伤。

If you're not moving forward, you're falling behind.

Happiness is not the belief that we don't need to change; it is the realization that we can.

Sometimes you can do everything right and things will still go wrong. The key is to never stop doing right.

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.
