"A book is a door, and every reader walks through it differently."

这个世界极其危险、不可信任、不可靠。

Fear can be a useful signal, but it shouldn't be the only voice we listen to.

I'm not a role model. I'm a father, a husband, a son, a brother, a friend. I'm a human being. I make mistakes. I have flaws. I'm not perfect. But I try to be the best person I can be.

The only thing that stands between you and your dream is the will to try and the belief that it is actually possible.
