Is very difficult to improve upon perfection.
If you have the ideas in your head that your (product, tool, process, organization, whatever) is perfect, or even close to perfect, you're not going to have the right mindset to improve it.
Even if it was perfect at some point (highly unlikely), it's probably not now. A commitment to continuous improvement is the hallmark of a true craftsman. You have to accept the fact that everything you do is a hack; A workaround until you can find another way that's less hacky. That's not to imply that you shouldn't make it as good as you can get it...you should. You just need to realize that it can always be made better.
