What do I love about writing?
The power.
It's really as simple as that. When I'm writing I have complete control - over the world, the events, the characters' destinies, and I can create a world that is thrilling and wild and absurd and beautiful if I want. And I can live there. Maybe it's only for an hour at a time, but I can live and feel and experience so many things, just by using my brain.
And it's not just the power over myself and my characters, but the power over my readers. This isn't a vicious, vindictive sort of power, it's just love. I want to take them and shake them up and make them laugh and make them feel, and then, in the end, make them feel satisfied, whether it's a happy satisfied or a sad one.
So, yeah, if I didn't have writing I'd probably be a megalomaniac of some kind. :D
