“The best thinking has been done in solitude. The worst has been done in turmoil.”

All bibles are man-made.

Everything comes to those who hustle while they wait.

If we did all the things we are capable of doing, we would literally astound ourselves.

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

Be courageous! Have faith! Go forward.

I never quit until I get what I want.

Genius is not inspired. Inspiration is perspiration.

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

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

There seems to be no limit to which some men will go to avoid the labor of thinking. Thinking is hard work.

Anything that won’t sell, I don’t want to invent. Its sale is proof of utility, and utility is success.

Time is really the only capital that any human being has, and the only thing he can’t afford to lose.

Great ideas originate in the muscles.

There is no expedient to which a man will not go to avoid the real labor of thinking.

Continued innovation is the best way to beat the competition.

Everything comes to him who hustles while he waits.
