人活一辈子，总会犯错误。

If you live long enough, you'll make mistakes.

人活一辈子，不能活得太庸俗、太单调。

People live a lifetime, cannot live too too drab, vulgar.

我们每一个人活是活在每一天的，假如说你每一天不高兴，你把所有的每一天组合起来，就是你一辈子不高兴，但是假如说你每一天都高兴了，其实你一辈子就是幸福快乐的！

Everyone live live in every day, if every day you upset you every day all combined, is your life happy, but if you happy every day, in fact, your life is happy happy!
