You haven't taught until they've learned.

Each of us has a huge capacity to learn and to achieve. Being ever alert makes the task of becoming all we are capable of becoming so much easier.

When you are through learning you are through.

If you're not making mistakes, then you're not doing anything. I'm positive that a doer makes mistakes.

There is no pillow as soft as a clear conscience.

Never try to be better than someone else. Learn from others, and try to be the best you can be. Success is the by-product of that preparation.

Climb the mountain so you can see the world, not so the world can see you. Focus all your effort on what is in your power to control.
