Gosh, I feel sort of weird asking for advice on this but here goes...
I'm actually writing a graphic novel at the moment and I'm sort of afraid that my main character is becoming too much like me. My main character is a grouchy, misanthropic aspiring science-fiction writer stuck in a dead-end job at a thinly-veiled Starbuck's expy (called Apollo's...) who's being targeted by a gaggle of street performers/assassins who are after his cat.
I started with writing from what I knew (useless college degree, taking crap job to support doing what I love), went from there, and now I'm sort of afraid my main character's become me... only prettier and more interesting.
Anyway, help?
