Am I good enough?

I’ve submitted a query and/manuscript to 2 different houses hoping I could get my novel published as soon as possible. I’ve been rejected by both. I felt so depressed all last week about it. The last one suggested that I use the first few chapters to grab the readers’ interest. I’ve been debating about either rewriting the fist few chapters or trying another publisher. All my friends and family members have given me so many words of wisdom. A co-worker said, “You’ve written a book. That’s something extraordinary. You should be proud.” A good friend said, “That’s the second time you’ve tried. If it was that easy, we’d all be published.” My son said, “Every time you’re rejected, you’ll learn something from it. It will result in you being a better writer.” I thought that was an amazing way to look at it and I’m surprised it came from my 19 year old son. I still felt like I wasn’t good enough and I worried that I may never be good enough. I’m used to falling and I’m used to getting up, brushing myself off and continuing on. I don’t give up…but this truly has brought me down. 6.5 years ago when I started writing the book I dated it for 2013. Somehow I knew it wouldn’t be finished until then. Maybe it’s just not finished yet. I’ve decided to continue writing the second book and I’ll slowly work on rewriting the first book. Maybe if I put it away for a little while then reread it in a few months it’ll be evident as to what to change, add and/reinvent.
