Don't be afraid of making mistakes, be afraid of not learning.

每一本书都是通往另一个世界的门，每一个读者都是旅行者。

And I urge you to please notice when you are happy, and exclaim or murmur or think at some point, 'If this isn't nice, I don't know what is.'

Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.

I'm not afraid of the future; I'm afraid of the past.
