Basically I'd change almost everything. I feel like I came off the assembly line with no advantages, nothing. Most of my life I've felt like a lemon of a person, or not a lemon but a bad, underpowered design in the first place, where I'm not broken, everything is working right, it's just not very good. As a kid I was able to escape those feelings with toys and fandoms, and took comfort in the knowledge that I had the rest of my life ahead of me to figure it out, to just randomly "get it" someday, or for me to get a lucky break like most people seem to. But it's been a long time since those things worked.
