Yesterday, I talked about the struggle of writing. How you have to learn to enjoy the struggle of writing to write productively. I would be remiss to not mention the joys, though, and there are many.
The joy of creating a world for a characters. Playing God as it were. The houses go there, the people go there, she loves him, he loves someone else even though she's not write for him, oh let's add in a few vampires and zombies and a flaming sword.
The joy of a scene saying exactly what it did in your thoughts. Of having the emotional impact that you intended for it to have. The satisfaction of the words flowing, and the written words match to the movie in your mind.
The joy of other people entering your world and finding it good. Of them getting excited about your words and your characters. Becoming your fan.
Awesome. Simply awesome. I recommend it to everyone.
