I'm really good at a variety of things, and I'm able to figure most things out pretty easily. However sometimes I do the dumbest shit. I'm awful at finding things, I can look right at something and miss it. Sometimes I've been looking for my shoes for 15 minutes and they're on my feet. This Gary Larsen cartoon pretty much summed me up as a kid:
As the above indicates, it's a common piece of wisdom that intelligent people can be pretty dumb, too. There are all kinds of intelligence, and no one has them all. And everyone has something.
The dumbest I am is with drugs. Some of my loved ones are incredulous that I could do some of the stuff I do and have done, despite constantly experiencing negative/destructive side effects to my life.
