I’m not a person who is happy just because I’m successful.

我不让过去拖累我，我让它教导我。

森林面临的最大威胁不是砍伐，而是漠不关心。

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.

注释：怨恨产生于不能容忍他人的小过错，祸患产生于事先没有谋划。
