i've started writing too

i've heard that it's seriously hard to get a book published.
and even if you do get it published, if your book is regarded as crap by the public then you'll find it even more difficult the next time round, as the publishers don't want to risk wasting time with someone who isn't gonna make them big money.

if you do write a book you should go over it again and again and again.
if you're part of a book group then get them to read your work and give you feedback, so you can edit your work as necessary. and it wouldn't hurt to pay a professional reader to look over it for you as well.

anyway good luck
