Knowledge talks, wisdom listens.

Fool me once, shame on you. Fool me twice, shame on me !

The mind is like a parachute. It doesn’t work unless it’s open.

Guns don’t kill people — people do.

He who knows others is wise. He who knows himself is enlightened.

If you are not part of the cure, then you are part of the problem.

The only time you run out of chances is when you stop taking them.

The best things in life are not things.

Growing old is ineveitable, growing up is optional.
