A man, though wise, should never be ashamed of learning more, and must unbend his mind.

Rich people without wisdom and learning are but sheep with golden fleeces.

Take these things to heart, my son, I warn you.
All men make mistakes, it is only human.
But once the wrong is done, a man
can turn his back on folly, misfortune too,
if he tries to make amends, however low he's fallen,
and stops his bullnecked ways. Stubbornness
brands you for stupidity - pride is a crime.

You will have believed, and have not hearkened unto me, to walk between the most subtle I walk because I had the love of my daily account of the journey

We can learn much from others and use that information to improve our world.

If you think you know everything,
there's nothing else to learn, until you learn...you don't know everything.
