> 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.
