Don't put limitations on yourself, other people will do that for you, don't do it to yourself. Don't bet against yourself, take risks. NASA has this phrase they like, “failure is not an option”. But failure has to be an option, in art and in exploration, because it's a leap of faith. No important endeavour that required innovation was done without risk. You have to be willing to take those risks. So that is the thought I would leave you with, “in whatever you are doing, failure is an option, but fear is not.”
