Sometimes those fantasies are fun and quirky, some are filled with creatures that haunt our dreams, while others feed a need that we are missing in our lives. Mine are the creatures that haunt my dreams.
I can pull them out and dust them off and then kick their butts until they are no longer a threat to my inner child. Does this sound like a a bunch of psychological bull crap then so be it. My suggestion is you sit down and start writing down what is in your head and see what you come up with. The creatures from your id will come flooding forward and pour out into what your writing.
As for my inner child, well she probably needs to be pulled out and dusted off and have her butt kicked as well. Hey I've admitted it before and I'll admit it again. I'm nuttier than a fruit cake and not ashamed to admit it. I'm also a weird, morbid, and a little wicked. Go me.
Anyway at this point I'm tired and will be even more so by the time I finished this book. As you get closer and closer to the end the culmination of all your work is here and you, like your reader, are dying to see how it will come out. I know the writer always knows but I don't believe that for a minute. I may have an idea how or know which way I want it to go but until I put the last punctuation mark on my story I really have no idea where it will go.
What I do know is that I wouldn't change this turn my life as taken. I write for myself. I do it because I enjoy it. I hope that my mind stays active and that I will be able to produce stories that I love and am proud of.
So the next time you tell yourself you want to write a story my advise it to sit down and start writing. You never know what amazing journey you might find yourself on and who knows, you might became the next great author.
