We perceive the world in terms of its utility for our survival.

要理解未来，首先必须理解过去。

The world is full of people who have dreams and the world is full of people who have ideas, but the world is also full of people who never do anything about them.

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.
