True leadership is about serving others, not yourself.

They are not monuments, but footprints. A monument only says, 'At least I got this far,' while a footprint says, 'This is where I was when I moved again.'

心理学唯一有效的数据是可观察的行为。

The most dangerous lies are the ones we believe about ourselves.

生活就是要抓住机会并为之努力。
