About being okay at most things

I'm the type of person who does pretty well at school - some might say really well - and would consider myself reasonably talented at a few things. I like to write and don't think it's awful, I draw when I find the time, I read whatever I can get my hands on (well used to but that's another post for another time) and wouldn't call myself stupid.
Now comes the petty part. I'm not actually great at one thing. I can create things that some people enjoy, I can get grades between an A minus and B on a semi-regular basis and I think I have some interesting thoughts on stuff but there was always someone better. Yeah, I know, I warned you this was going to be petty.
But here's the thing, if someone is always better than you, what makes you special? What makes you interesting? Everything I do is something a lot of other people could do as well, a lot of them probably even better. This is especially true for school where, for a long time and even still sometimes, I would be one of the best in class and unable to fully be proud of myself because if someone else managed to be better then I couldn't really be proud, could I?
This doesn't really have a moral attached to it because let's be honest, I still have to figure it out myself. But I do think that everyone is special and interesting, whether they have something great to offer or not. Someone might be able to write better than me (ok, tons of people can) but I still came up with a concept, original or not, and the words I'm writing are coming from me, not someone else and that's enough to make them different and worth creating. The things I draw aren't masterpieces, not by a long shot but they are something that brought me joy, some reflect what I was thinking and some I think look pretty. And all of that's valid. Even this blog is something I can do and appreciate, no matter how many better, more interesting blogs are out there (while on the subject, I should probably stop word vomiting when writing these things and actually think about what I want to say first).
What do you do that might not be great but still worth being proud of?
