四十不惑英语

The Master said, At fifteen I set my heart upon learning. At thirty, I had planted my feet firm upon the ground. At forty, I no longer suffered from perplexities. At fifty, I knew what were the biddings of Heaven. At sixty, I heard them with docile ear. At seventy, I could follow the dictates of my own heart; for what I desired no longer overstepped the boundaries of right.

At thirty I stood firm; (三十而立) At forty I had no more doubts; (四十而不惑) At fifty I knew the mandate of heaven; (五十而知天命) At sixty my ear was obedient;（六十而耳顺）

Confucius said, one should be independent at thirty, wise at forty, understand his fate at fifty, enjoy everything at sixty and be unbounded at seventy.
