An inventor is simply a fellow who doesn't take his education too seriously.

I don't want men of experience working for me. The experienced man is always telling me why something can't be done. The fellow who has not had any experience is so dumb he doesn't know a thing can't be done - and he goes ahead and does it.

Believe and act as if it were impossible to fail.

The world hates change, yet it is the only thing that has brought progress.

Every great improvement has come after repeated failures. Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. One fails forward toward success.

Every time you tear a leaf off a calendar, you present a new place for new ideas and progress.

Whenever you look at a piece of work and you think the fellow was crazy, then you want to pay some attention to that. One of you is likely to be, and you had better find out which one it is. It makes an awful lot of difference.
