>>1 You need to grow up. I'm not just saying this to be an ass, though. I've been in roughly the same spot you are, and I can tell you that you have a family that actually cares. I was kicked out on three separate occasions. Not "being one of them" is a pretty piss poor excuse when they try to include you. I mean, seriously? "They took away my wifi." Know what my family took away from me? A place to live. Not only this, but you apparently have a cozy home, so it's not like you're hurting for the necessities here either.
Now career choices. You don't know what you'll do so you'll just become a writer then? Shit doesn't work like that. You don't just "become a writer". How the hell do you think you'll ever compete with the people who love writing? People are out there who's only passion is writing, and you think you can just "become a writer?" Give me a break. If it's a dream, pursue it, but you don't even sound slightly interested.
You want real advice? Grow up.
