If people ridicule you, look them in the eye and say, 'Yeah, I may have failed, but at least I tried,' and get on with it.

You can't look at the problem and say, 'I want them to do more, better, faster miracles - and not invest in research, not invest in development, and have those miracles delivered to me free.' It's unrealistic.

I took the California Highway Patrol exam and didn't pass, so I tried to be a cop and failed.

I've never regretted anything I've done, even the things that I've failed at. I've often regretted not trying something really big, because you'll never know.

If I had the uniform on, you didn't doubt for a moment I was a pilot. No one ever blinked an eye if I tried to cash a cheque wearing that uniform.

I want to look back on my career and be proud of the work, and be proud that I tried everything.
