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

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

The distance between two minds is understanding.

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

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

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.
