Ingenuity! Don't leave home without it!
I just read one of the most awe-inspiring stories ever this morning. I usually read MSN.com news every morning, to keep up on things, feed my story-producing subconscious, and to have stuff to talk about with my 17-year-old, Shiloh. Shiloh has gotten quite interested in the things that are going on out in the world, and constantly challenges my knowledge base (he can look things up on the internet and make sure I'm right!).
Anyway, the story I've linked to below will blow your mind. And it should get every writer out there thinking about ways to self-promote (and I've already got three novel plots out of it!).
