【讲解】：我十五岁时开始立志学习，三十岁时能立足与社会，四十岁时能通情达理遇事不再疑惑，五十岁时懂得了天命的道理，六十岁能听的进不同的意见，到了七十岁时已经达到随心所欲，想怎么做就怎么做，也不会超出规矩。

When men are most sure and arrogant they are commonly most mistaken， giving views to passion without that proper deliberation which alone can secure them from the grossest absurdities.

Change your thoughts and you change your world.
