Being busy does not always mean real work.

Religion is all bunk.

I make more mistakes than anyone else I know, and sooner or later, I patent most of them.

An idea is something that won't work unless you do.

Of the 200 light bulbs that didn't work, every failure told me something that I was able to incorporate into the next attempt.

My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

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