Redefine what perfection is (although I'd argue you'd probably do well to work on disabusing yourself of the idea of perfection altogether - but that's for another time).

Back to redefinition: what's perfect for you may not be what's perfect for your team, your division, your line of business, your company, your personal project, whatever. Is part of the perfection metric time to deliver? Customer (user) satisfaction? Reduction of support requests? I'm not saying any one of these is right, but I believe there's a framework of compromise out there that can help you should you want to change this area of your professional life. In short, think outside the core problem and expand the radius of context from just you and that notion of perfection, to something larger, something more systemic - I believe that can help.

On the other hand, if your drive for whatever you believe perfection is, works for you, then, meh, do you! We do need folks to scream that x or y isn't good enough, even if only to evaluate if we should find a better compromise than the current one.
