What's it like inside an ADHD brain?

My good friend asked me to explain what is it like to have ADHD, so I'm doing my best to explain the chaos inside my brain. How can I concentrate on anything with this level of commotion? Good question. Sometimes I wonder myself, ha! I also share a few ideas on how to calm the storm inside, like ADHD medication, routines, life skills, white noise and a whole lot of trial & error.
