This one seems a bit counter-intuitive, but it's important. Lots of perfectionists are afraid of failing, and therefore only do the things they know they are good at. Don't succumb to this mindset. Creativity is like dating: If you never strike out at least some of the time, you're not trying hard enough. So let go of your ego, be prepared to fail (but don't expect it), and jump into new and challenging situations. You're never going to be creative if you never take a leap.
