I recommend giving this a good hard look first: http://gailsimone.tumblr.com/post/4654769851/brutal-tips-on-breaking-into-comics-warning-long
I am a bit concerned about the “think I’d like to write,” to be honest. This is something that takes a lot of passion and commitment. It’s difficult to break in, and difficult to STAY in once you have broken in. So please give all that a serious look and figure out a plan of attack.
Not trying to scare you off, but this is tough stuff, and I want people to be prepared.
Good luck, and thanks for reading bop!
