"Curiosity. It's the most powerful thing you own. Imagination is a force that can actually manifest a reality. And the respect of your team is more important than all the laurels in the world... Don't put limitations on yourself. Other people will do that for you – don't do it to yourself, don't bet against yourself, and take risks.
NASA has this phrase that they like: 'Failure is not an option.' But failure has to be an option, because it's a leap of faith. And no important endeavor that required innovation was done without risk. You have to be willing to take those risks. So, that's the thought I would leave you with, is that in whatever you're doing, failure is an option, but fear is not." - James Cameron
