What happens after you finish writing a book (at least, if you’re me):
I DID IT! =D
Um. But now it’s OVER. : ( And I miss my characters. :~*( And I don’t know what to work on now. {:/ Oh NO! Am I going to be one of those writers that only writes one novel they’re happy with and then can’t follow up with anything good ever again??? {:E
No. That’s not me. I won’t let it be. I’m going to sit down and write something else RIGHT NOW to prove that I’m not one of those writers. 
Um. I don’t know what to write about, though. I don’t like any of my other ideas because they’re not as polished as the ones I just wrote about. {:/ But those ideas weren’t polished, either, until I finished writing and refining and editing the book! I can do that again. : )
…I don’t like these characters as much as my characters from my last book. They aren’t cooperating with me like the old ones did. }:( $#&@ you, new characters! $#%& you for not being the characters from my last novel!! You aren’t as good! >:# *throw notebooks in the corner* *ignore writing for a month or two* *do other stuff until your writing gets jealous because you’re not paying it enough attention*
Oh! I have an idea! And I really like it!! {=D Shhh! Don’t spook it! Sneak up on it quietly. ; ) *sneak, sneak, sneak* …aaaand POUNCE! Gotcha! =D

I had a similar experience after writing my first book. My books are like children to me. It’s hard to say “that’s it”. But it’s also really rewarding to know what you’ve accomplished. You’ve just got to wait for another idea to pop into your head! Don’t force it. Are you going to try to get your book published? I’ve moved on to another story by now that I think will be more successful than my last, which was too unconventional, and perhaps too personal, to be published. Good luck!
U ah soooo cwaizee! 😀
