Yes, very much so. Most of my achievements are quite small. I'm happy with that, just plugging away to make my life a little bit easier here and there, usually by finding a solution to some minor problem that's annoying me. Possibly my musical achievements are bigger, but the size of the project doesn't much matter to me. One big thing or a lot of little things, not a lot of difference really. If you mean achievements as per the stereotypical mainstream life goals, not so much - if by coincidence I happen to want something that's also a big mainstream measure of a person's worth, then yes, but if I don't then I don't bother with it, and if I do, I'm no more proud of the result than I would be about some small or unusual goal of my own.
I've noticed that achieving something or other is very important to my feelings of well-being. I can't seem to settle for just being a spectator, I've got to do things, try things out and see how well I can do. If I'm not rising to a significant challenge, I'm not happy. I get very perfectionist about it, I always want to make the result a bit better than just good enough. The satisfaction from my achievements is usually short-lived. One I get used to the surprise of having got my result, I'm unhappy again. But sometimes an old achievement can get a new lease of life if somebody else sees it and seems to admire it. So I suppose I see impressing others with my intelligence and skill as an achievement in itself, though I don't plan it to happen and it doesn't happen much, probably because few people would be interested in the minute details of my interests, which tend to be very specialised and hard for others to understand or see the point. It's a shame I can't share more of it, but I guess my thinking style and preferences are too unique for that, and I can't imagine that will change.
I think it's more than just pride though. It's a more general satisfaction and a feeling that I'm really living while I'm chasing a result and pitting my wits against the chaos of my environment. It's the battle, and it's those moments where after feeling stumped something occurs to me and I think "hang on, I think if I just tweak this here I can turn this situation round." I find that exciting and when I get such insights I can hardly wait to try them out. Having a human brain and using it to solve problems is something I never get tired of, as long as it seems to be getting me somewhere.
