Wisdom acquisition is a moral duty. It’s not something you do just to advance in life. And there’s a corollary to that proposition which is very important. It means that you’re hooked for lifetime learning, and without lifetime learning you people are not going to do very well. You are not going to get very far in life based on what you already know.

Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
