My personal motto is: “don’t chase perfection, and don't settle for mediocrity“. I can’t just ship the most basic thing because I find that boring and demotivating. I don’t like to make good enough things. I take joy in going a little deeper into things. But chasing perfection is a never ending road.

What helps me is to write down my vision of an mvp. As I start to work on it that vision may change. I may think of this or that feature. If I get that itch to add something new, I go back to that document. I ask myself if this is really a critical addition. Sometimes I come to the conclusion that yes, this new way of thinking is the way to go. Most times I just write it down as something to explore in the future and keep going.
