Silence & Smile are two powerful tools. Smile is the way to solve many problems & Silence is the way to avoid many problems. 【微笑和沉默是两个有效的武器:微笑能解决很多问题,沉默能避免许多问题。】
Remember what should be remembered, and forget what should be forgotten.Alter what is changeable, and accept what is mutable. 【记住该记住的,忘记该忘记的。改变能改变的,接受不能改变的。】
