At fifteen, I had the will to learn; at thirty, I could stand; at forty, I had no doubts; at fifty, I understood the heavenly Bidding; at sixty, my ears were opened; at seventy, I could do as my heart lusted without trespassing from the square.
translate: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
