I shall make electricity so cheap that only the rich can afford to burn candles.
Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.

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

They say President Wilson has blundered. Perhaps he has, but I notice he usually blunders forward.

There is far more opportunity than there is ability.
I never did a day's work in my life. It was all fun.
To invent, you need a good imagination and a pile of junk.
Waste is worse than loss. The time is coming when every person who lays claim to ability will keep the question of waste before him constantly. The scope of thrift is limitless.
What you are, will show in what you do.
