Okay, so you have finally finished your first ever novel! You have read it. You've asked someone with remarkable editting skills to look for any problems, and you've had a small number of beta readers try it out. Your book recieves high marks, and people feel confident you may have a future in the business. Of course now in this day and age, you have options. eBooks are taking off, and self publishing is easier than it's ever been. Maybe you go to Amazon frequently, and you have researched not only their opportunities on publishing through the Kindle, but also have noticed an affiliate of theirs, CreateSpace, which allows you to self-publish a physical copy of your book to put on sale.
Of course if you can succeed in signing an Agent and a Publisher chooses your work, then marketing, distributing and more are covered without anything additional needed from you. Maybe you're the next big thing, and your publisher sends you to book signings, cons, and who knows what else?
I personally can't answer this question. I am one of the new guys, and my work is not finished yet, but will be in the next few months, but I think this scenario is something to talk about. What do you think? If you're in the same boat as me, then what direction are you considering taking? Let's not see any comments about "The book industry is tough, and more people don't make it than do". We all know that already. Don't give up and keep that glass half full!
