Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.

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

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

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

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

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