Never get stuck with the thing that ruins your day. Stay upbeat and be happy; for life is too short to be wasted on crap.不要让不好的事情毁了你这一天，乐观一点，开心一点，生命如此短暂，别浪费时间在不值一提的事情上。
For something,we can't understand when we are young but by the time we understand,we are no longer young. 有些事情，当我们年轻的时候无法懂得，当我们懂得的时候已不再年轻。
Being happy does not mean that everything is perfect, It means that you have decided to look beyond the imperfections.
学习虽易，学会不易，且行且珍惜。
