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

Thomas Alva Edison

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

I think work is the world's greatest fun.

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

I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

As a cure for worrying, work is better than whisky.

I never did a day's work in my life. it was all fun.
