You have to believe in yourself when no one else does.

Every book is a door that opens onto another world, and every reader is a traveler who steps through it.

Success is not about how much money you make, but how many lives you touch.

无论多么复杂或精细，所有行为都可以用刺激和反应来解释。

成功就是喜欢自己，喜欢自己所做的事，并且喜欢自己做这件事的方式。
