It starts with this. I get my inspiration from stories from anime. I watch them on the regular basis and I get most my inspiration from them. Almost Half of the authors on this site does. The previews I use in my book "The Mysterious Life of Jamboree Ryken" are inspired by adult swim promos. Mainly for Toonami, an anime program that comes on every Saturday night from 10:30 to 4 in the morning, or depending on which anime changes its schedule. I use the music that's from its soundtrack our random dubstep.

This is just how I write my stories, not everyone has to write what others right. Like I said before write how you want to write. I hope this is good enough advice. If so we can argue about it in private messages.
