It is a first principle of human action that a man does what he believes will satisfy his desires.

The principle of asceticism never was， nor ever can be， consistently pursued by any living creature.

"When you follow your heart or your gut, when you really follow the things that feel right to you, you can never lose."

The mind is the organ of possibility in a world of challenge.

游戏的力量在于它能让人体验到现实中无法经历的事情。
