人生就像骑单车，想保持平衡就得往前走。

实现真正自由的唯一途径是通过自律。

Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something， return it better shape (filled up， cleaned) than when you got it.

衡量一个人的真正标准是他如何对待那些对他绝对没有好处的人。

The only real journey is the one within.

Profitability and sustainability are not opposites - they're two sides of the same coin.
