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.

I was as hollow and empty as the spaces between stars.

生命从世界得到资产，爱情使它得到价值。

Courage is grace under pressure.

永远不要让自尊心妨碍你在需要时寻求帮助。
