A few years ago I had lunch with an old co-worker who shared with me her amazing idea for a scifi /fantasy story. I'm mean it was amazing.
I ran into her today and asked how the book was coming along and she said, "Oh no one was really into it. I didn't wanti waste my time on an idea that no one liked."
"What?!?" I said, "I liked it, but more than that YOU loved it! Who cares what the small minds in your circle perceive as 'good' or not. They are idiots. You liked it and that is all that mattered. I'm sorry that you wasted all you time listening to them instead of having a manuscript or book right now to brag about."
Write, because you are a writer. People will love some things and hate some things, let it all slide off your back. As a writer you must write what you are compelled to.
Today's "not-so-great" story idea can be next years best selling novel. Let no one take your storyies from you.
Keep writing my friends!
Cheers to you!
