Life is 10% what happens to you and 90% how you react to it.
真相很少纯粹，也绝不简单。
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.
Every book is a kind of journey, and every journey changes you.
