It should not be hard for you to stop sometimes and look into the stains of walls, or ashes of a fire, or clouds, or mud or like places, in which...you may find really marvellous ideas.

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

I don't force it. If you don't have an idea and you don't hear anything going over and over in your head, don't sit down and try to write a song. You know, go mow the lawn...My songs speak for themselves.

Many a man fails as an original thinker simply because his memory is too good.

Kick-start your brain. New ideas come from watching something, talking to people, experimenting, asking questions and getting out of the office!

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.
