“Everything comes to those who hustle while they wait.”

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.

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

I start where the last man left off.

I am 67, but I’m not too old to make a fresh start.

Each time you fail, you have eliminated another wrong option.

I’ve realized that most of my best ideas have followed a good night’s sleep.

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.

Work while others are wishing.

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

Know your enemy and know yourself and you can fight a hundred battles without disaster,

Conceal your dispositions, and your condition will remain secret, which leads to victory; show your dispositions, and your condition will become patent, which leads to defeat.

It is not enough that we do our best; sometimes we must do what is required.

Opportunities will be available to you that you cannot imagine.

Each success brings with it the potential of failure and each failure brings with it the potential of success.

Never venture, never win!

Suffering is the essence of success!

We don’t know what the future holds, but we do know Who holds the future.
