I have!
They are great because you get to be an adult and that's actually quite neat! Lots of freedom, and people start to respect you at least a bit (not everybody, though. Older adults might still treat you like a kid). Mentally it can get pretty difficult to some because of the standards put on adulthood might make you wonder if you should 'have achieved X or Y' by now (don't forget to remember X and Y are one of million of things that have value out of everything you can achieve. Sometimes just being a good friend or being content or happy is more than enough!) but it also goes away with time, so be kind on yourself.

Should I worry about what I'm currently doing? like I've made a Miku Miku Dance animation, at this point I kinda worry that people think it's weird for some one in their 20's to do MMD animations(yeah I could not care but I'm sure it's going to harm me if I don't care enough in certain situations)
