Absorb ideas from every source.

Most of my ideas belonged to other people who never bothered to develop them.

Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time and opportunities.

My principal business is giving commercial value to the brilliant - but misdirected - ideas of others.

I am long on ideas, but short on time. I expect to live to be only about a hundred.

Keep on the lookout for novel ideas that others have used successfully. Your idea has to be original only in its adaptation to the problem you're working on.
