To do much clear thinking a person must arrange for regular periods of solitude when they can concentrate and indulge the imagination without distraction.

I have had a lot of success with failure

One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

My main purpose in life is to make money so I can afford to go on creating more inventions.

When you become quiet, it just dawns on you

I never did anything by accident, nor did any of my inventions come by accident; they came by work.

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