I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're doing something.

The most important thing is to keep your mind active.

The only thing we have to fear is fear itself.

思考你现在的幸福，每个人都有很多；而不是过去的苦难，每个人都会有一些。

The key to deep learning is to have lots of layers in your neural network.
