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.

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

The ideas I use are mostly the ideas of people who don't develop them

If there is a way to do it better...find it.
