The chief function of the body is to carry the brain around.

Discontent is the first necessity of progress.

To my mind the old masters are not art; their value is in their scarcity.

I start where the last man left off.

The value of an idea lies in the using of it.

We often miss opportunity because it’s dressed in overalls and looks like work.

I don’t live with the past; I am living for today and tomorrow.

There’s a way to do it better - find it.

I readily absorb ideas from every source, frequently starting where the last person left off.

There is no substitute for hard work.

Success is 90% perspiration and 10% inspiration!

To have a great idea, have a lot of them.

What you are will show in what you do.

I’ve never made a mistake. I’ve only learned from experience.

Never get discouraged if you fail. Learn from it. Keep trying.

I find out what the world needs. Then I go ahead and try to invent it.
