Aaron Swartz in a great piece called Steve Jobs and the Founder’s Pain:
Something that’s perfect just feels much, much better than something that’s almost right. When I’m doing something myself, I can just sit there and work at it until it’s exactly right. It’s embarrassing to launch a product with a bug in it! It physically hurts when I realize that’s what I’ve done. But as projects and companies grow, there are more and more people in between me and those tiny details. And then I face a choice: do I keep complaining until something’s perfect or do I just let go and consider it somebody els’s problem?
The people who are not content to make it somebody else’s problem are the ones who end up changing the world.
