Here's something you may not know about me... I've been playing guitar for well over 20 years.
I'm not particularly great at it, but I can pick the thing up, and I can play some stuff on it. I love it.
This might sound strange, but when I'm working... when I'm writing... I'm often standing at my computer noodling around on the guitar while I brainstorm. It helps me think. Being able to play a little riff between the gaps in my thinking helps to keep me focused, and keeps my head from going blank.
