成功不是幸福的关键,幸福才是成功的关键。
Success is not the key to happiness. Happiness is the key to success.
We are all connected; to each other, biologically; to the earth, chemically; to the rest of the universe, atomically.
这就好像口渴了才挖井,人死了才找医生。 
We are all descendants of successful ancestors; failure left no progeny.
