Few things need to be perfect to succeed. And that's good, because in our inherently flawed, topsy-turvy world, few things can ever approach a state you might call "perfect." You can waste a whole lot of time trying to perfect the non-perfectable -- especially if you're working on a thing that's already good to go.
Is the pursuit of perfection holding you back from success? Is there something in your life that is "good enough" to enjoy, to relax about, to launch, to let fly into the world?
