Sorry to hear that Wruter. Words written are never a waste. I have countless short stories completed that will never see the light of day and at least three book ideas started and stopped, so don't worry about it. And you're right. It isn't easy. I hope you stick around this site. There are so many great things to help with your growth here. Check out the writing challenges in the writers forum, and join the conversations in the General Writing Discussion and Critique area. Or just have some fun in the Lounge.
I am just gearing up for some serious writing today. I have the house to myself (and a sleeping dog) so I am going to try to get something done. Maybe get caught up this weekend. My writing today is on a project I need to get done for the end of the month, so my book will have to wait until that is done. I did pass the 30,000 words last night, and my book is over 40,000 now! Feels good for a new novel writer.
