Starting my first Novel

I'm excited to say that I'm actually starting my first(and probably last) full length novel. Titled 'The Road to Nowhere', It's a story concept that I haven't been able to get out of my head for a long time now. I feel that when the universe gives you a certain nudge, you have to act on it or else you risk not living up to your fullest potential. I've never actually done this before because, as you know, I prefer writing short stories. There's always the risk that you, as a writer, will lose the audiences attention if you drag a story out further than it's supposed to go. So, I don't know what to expect from this particular story. Hopefully, all goes well.
