I think the most important thing is to be true to yourself.

向人求助之时应该去求真正胸襟开阔的人；帮助别人时要帮助真正需要帮助的人。

天真是一种疯狂。

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.
