We haven't failed. We now know a thousand things that won't work, so we are much closer to finding what will.

Do the thing and the power will come.

Opportunity is missed by most people because it is dressed in overalls and looks like work.

I have had a lot of success with failure

When there's no experimenting there's no progress. Stop experimenting and you go backward. If anything goes wrong, experiment until you get to the very bottom of the trouble.

I failed my way to success.

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