Sam, I am a writer also. I belong to a writers group (a must for a writer) and we recently had a speaker who has a (relatively) famous book out and he said the most fun you will EVER have with your writing is not getting the agent, not getting published, but doing the writing.
Another friend in this group has a novel coming out in September and she is totally anxious about publicizing it, getting book signings, the whole business bit.
So just write on and enjoy what you’re doing. I’ve written a ton of stuff, 7 books, 8 screenplays, a lot of short plays, columns (published in a big daily paper for a year or two).
My problem is marketing my stuff. A couple of rejection letters and I blow it off for a long time.
When I was in high school and my father was encouraging me to write, he said he’d pay me a dollar for every rejection slip I got.
I though that was a clever way to get me to submit ideas and articles without putting too much pressure on me, especially considering how fickle the publishing world is.
