Undiagnosed ADHD. It's a thing. I'm 99% sure I have it. What it means for me is that if my mind isn't sufficently engaged by enough stuff, it starts to wander. It also means that drawing helps me focus. So when I'm in a meeting, sitting in church, on the phone... my hands want to draw, and it actually helps my mind stay focused on what is being discussed.
Sometimes cool ideas for paintings come out of those doodles. Sometimes cool ideas for drawings come out of those doodles. Sometimes the doodles themselves are just cool.
Some of those things live here.
