The mind is everything; you can go no higher than what you put into it.

Bad mind, bad life. Good mind, good life. Excellent mind, excellent life.

The mind is like a razor; it only works when sharp.

The day you stop learning is the day your mind starts dying.

The distance between two minds is understanding.

Money doesn’t help if your mind is poor; strength doesn’t help if your heart is weak; possessions don’t help if your soul is empty.
