After an operation, I know that medicine is not bitter at all, hard fall once, I know that chafing skin is not worth crying at all, betrayed, I know that quarreling two words do not hurt the true feelings.

十五、人生于世，委屈在所难免，消化了就是成长的动力，消化不了就会变成脾气。
Life in the world, grievance is inevitable, digestion is the power of growth, digestion will become temper.
十六、从今天起，做一个简单而幸福的人。不沉溺幻想，不庸人自扰，不浪费时间，不沉迷过去，不畏惧将来。
From today on, be a simple and happy person. Do not indulge in fantasy, do not worry, do not waste time, do not indulge in the past, do not fear the future.
