I love writing and think I might want to be a writer (of novels). I'm not sure if I want to do it full-time though. My other interest is in autism and other disabilities and mental illnesses, so I want to study that too.
I'm not sure if I can be a writer though. I don't seem to be able to stick with one idea long enough

I thought I wanted to be a writer for awhile when I was a kid (mostly I wanted to be a marine biologist, but, I was so bad in school I assumed I'd never make it through the coursework), but, I could never finish anything I started writing.
Eventually, I made my way into a technical field... it's filled with brilliant people, but, most of them are horrible with communication, especially written communication. Voila. I'm a writer and editor. Easy to get started and to finish because you have a defined topic and a clear deadline.
I'll never get rich doing it, but, I find it satisfying, and it provides a little financial cushion on occasion.
