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 righ.
ConfuciusWhen you see a good person, think of becoming like her/him. When you see someone not so good, reflect on your own weak points.
