Judging a perfect solution requires first asking, whose problem are you solving? If you only ever insist on addressing your own aesthetics and properties of interest, you're only solving your own problems, not a problem anybody else has. That can be fine sometimes, but probably not for all problems. People will appreciate solutions that save even 20% of their time now. Saving them 50% if only you could work on it for 2 more years has less value.
