I can't get round to writing because life gets in the way
Really? Life is getting in the way? Life? What is your life? Are you not a writer yet? Sorry, I mistook you for someone who was reading this garbage for a reason, why not click on one of the adverts below and go to someone else's website who'll give you lots of courage to give up?
You are a writer. You've begun the long process for a good reason – you had a story to tell. You still have that story, you've probably got a really good story. Hell, it might not be award winning, it may not find itself on the bestseller's list, but that's a pretty rubbish excuse from doing what you know you need to do – and that's write.
Write, write, write. You have nothing to lose. Stay up late, just an hour a day extra... it's not going to kill you, anyone who's "forcing" you to do otherwise doesn't hear your passion – let them know your passion and they will honour your needs beyond anything you can imagine, I swear it. Let them know they're going to become part of that wonderful first page of any novel:
"This book is dedicated to XXXXX XXXXXXXXXX who put up with me working long hours through the night when I should have been pleasuring them, instead."
