> Is that just an early-career thing, or is there some way I can get better at giving up the idea of perfection?

No, you just have to really, really get it into your head that perfection most often results in missed deadlines and never truly finishing anything.

One of my hot takes is that anybody that considers themselves a perfectionist but can also list off things they've completed doesn't actually understand what true perfectionism means. They're just bragging about their attention to detail.

Redefine what perfection is (although I'd argue you'd probably do well to work on disabusing yourself of the idea of perfection altogether - but that's for another time).

Back to redefinition: what's perfect for you may not be what's perfect for your team, your division, your line of business, your company, your personal project, whatever. Is part of the perfection metric time to deliver? Customer (user) satisfaction? Reduction of support requests? I'm not saying any one of these is right, but I believe there's a framework of compromise out there that can help you should you want to change this area of your professional life. In short, think outside the core problem and expand the radius of context from just you and that notion of perfection, to something larger, something more systemic - I believe that can help.

On the other hand, if your drive for whatever you believe perfection is, works for you, then, meh, do you! We do need folks to scream that x or y isn't good enough, even if only to evaluate if we should find a better compromise than the current one.

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.
