Don't just fight in the North or the South. Always imagine every battle in your mind, where everyone is both your enemy and your friend, and all possible events happen simultaneously. That way, nothing will take you by surprise, and everything that happens will be something you've already imagined.

Never invest in any idea you can't illustrate with a crayon.

I don't care what you think about me, I don't think about you at all.

成功并不是终点，失败并不是终结，只有勇气才是永恒。
