When I have eliminated the ways that will not work, I will find the way that will work.

When you have exhausted all possibilities, remember this - you haven't.

Just because something doesn't do what you planned it to do doesn't mean it's useless.

I have not failed. I've just found 10,000 ways that won't work.

The first requisite for success is to develop the ability to focus.

I never view mistakes as failures. They are simply opportunities to find out what doesn't work.

There is much more opportunity than there are people to see it.
