When I was like 13, I thought 20 seemed so old (to be fair, I couldn't picture myself going beyond 18 at the time) but even now I've been 20 for a while, I still feel like a kid. I'm sure this is partially because of autism, but I think it's also a sentiment a lot of neurotypicals share. I think that even at 30 I'll still feel young, which makes sense cus it is young! It's difficult to fully understand age, what is old and what is young, both because of my time blindness (the term time blindness is usually used for shorter periods of time, like forgetting appointments and losing track of time while doing something, but I think it also makes sense to use it in a longform context) and also because of society's general opinions on age (especially on women). There's probably less than 5 years of your life where you're the 'ideal' age by society's standards.
I'm a fifth of a way through my life (assuming I live to around 100, probably closer to a quarter more realistically) and yet I don't remember most of it. I suppose in some way that's normal, you're not expected to remember much of your childhood, but I still hope that I'll be able to remember more of my life from here on out. Through journal writing and such. I really love reading back on old journals, I only have one that I ever finished, and even though a lot of the writing is quite sad and distressing, I still like looking back on it. I do also have some text documents of journal entries I was doing for a while as well. Nothing seems to stick though, maybe this can? I have hope. I didn't mind doing the simple text documents as journal entries. I think the main thing is I struggle to find things to write about. I'm in my honeymoon era with the site so I'm writing quite a lot, but eventually I'll hit that wall of burnout and I won't know what to write about. Maybe that'll change with uni? I don't know, I guess we'll find out. I might end up doing the text document thing for more personal things that I don't want to put on the site (or things I'm too embarrassed to talk about).
