speaking as an A1 (not so far removed from the same position myself), I keep finding minor errors in things I've worked on after sending them out. But a minor consolation lies in the fact that I keep finding such errors even in work that PAs and Partners send out. Fewer errors but errors nonetheless. With the kind of hands-on work we do and the tight deadlines within which we work - it's only natural that some small typos and stray words tend to stick around 3-4 rounds of edits.

At a lower rung, our job is to get the meat of the details right - that will be the figures, basic logical flow of arguments and structure and language of your drafts. You'll master the smaller bells and whistles and finesse on your work only with time and experience. And even then, perfection is just an aspiration and not really an achievable standard when many heads and hands come together to make a work product.

I'm not saying that you become complacent towards the errors you make. But beating yourself up for messing up things that you've barely spent any time learning to do is not a constructive approach either. Your team with nice people knows this, and they are rooting for you and pacing you to become a formidable resource in due time.

The sense of disappointment, lack of self worth or any feelings of anxiety you feel are your own demons to conquer apart from that. Law firms make for challenging environments even without any of this baggage you bring into your work. Give yourself a fighting chance and don't bow out without a fight!
