"Done is better than perfect" is one of those beliefs we have for those of us who are prone to modding our projects in a neverending cycle. Will we ever finish what we started? Ben Barry, a designer at Facebook calls it a favourite quote so that a project can move ahead and follow through.
Perfection, can be an enemy of progress if not done right.
I have several friends that are incredibly talented. They will start on projects but rarely follow through. They get bored or distracted or discouraged that it's not "perfect" and give up. Following through and finishing things is one of the most important things you can learn.
One of my favorite quotes is "Done is better than perfect." That doesn't mean making crap – I believe you should always strive for the highest quality you can – but you have to finish. I think a lot of my friends in this situation don't realize how in-demand their skills are. I think if you follow through on projects and just put the tiniest little effort into promoting yourself and have the tiniest bit of self-confidence, you can get the job you want.
