The challenge with learning is that it is impossible for a man to learn what he thinks he already knows. It’s what we think we already know that often prevents us from learning. The mind is much like a parachute, it works very best when it is open. It helps to recognize that the problems we face today cannot be solved with the same thinking that created them. And, the secret to fixing the problems is to not focus all of your energies on the old, but to build upon the new.
