If everything seems under control, you’re just not going fast enough.

The happiness of your life depends upon the quality of your thoughts; therefore guard accordingly.

The critical ingredient is getting off your butt and doing something.

Success is a lousy teacher. It seduces smart people into thinking they can’t lose.

Keep on going, and the chances are that you will stumble on something, perhaps when you are least expecting it. I never heard of anyone ever stumbling on something sitting down.

What is not started will never get finished

You don’t learn to walk by following rules. You learn by doing and falling over.

I never think of the future

Nothing will work unless you do.

Purpose is what gives life a meaning.
