子曰：“吾十有五而志于学，三十而立，四十而不惑，五十而知天命，六十而耳顺，七十而从心所欲，不逾矩。”

——《为政》

Leah译

吾十有五而志于学，When I was fifteen I doted on learning

三十而立，When I was thirty I established myself in the society according to the manners

四十而不惑，When I was forty I was no longer vexed by earthly affairs

五十而知天命，When I was fifty I knew what was predecided by fate was not within my reach

六十而耳顺，When I was sixty I was able to accept opinions of various kinds

七十而从心所欲，不逾矩。Now I am seventy,

 I can do what my heart desires without overstepping any bounds.

白话文：

我十五岁就立志学习，三十岁就能够按照礼仪的要求立足于世，四十岁遇到事情不再感到困惑，五十岁就知道哪些是不能为人力支配的事情而乐知天命，六十岁时能听得进各种不同的意见，七十岁可以随心所欲(收放自如)却又不超出规矩。
