Life is a series of lessons which must be lived to be understood. (Thomas Carlyle, 19th century British philosopher)
As Carlyle suggests, lessons are best learned, not by rote and lecture, but by experience. The accumulation of valuable knowledge is the result of lots of living. And no one should try to avoid such learning. To put it simply, to live is to learn. The secret to good learning, then, is to pay careful attention to life’s experiences, using reason and wisdom to make them most beneficial.
Intelligent people are always ready to learn. Their ears are open for knowledge. (Proverbs 18:15)
