Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
走出去不是目的,走进去才是我们的目标。
出自先秦《荀子·修身》。批评我而又批评得恰当的,他便是我的老师;肯定我而又实事求是的,他便是我的朋友;讨好奉承我的,他便是我的仇人。说明修身养性要有闻过则喜的雅量,要亲近正人君子而远离谄谀小人。这样,才会有利于自己道德的修炼进步。
