As a software developer, until I see something that I consider better, there is no reason to quit.

Sure, what I consider "better" is subjective.

Yet, what is missing more, "perseverance" or lack of it?

I think that the important thing is actually to love your crap, because you made it, it is self-expression.

If others don't like it, too bad, but as long as you like it, everything's just fine, keep going.
