“The Psychoactive Sound Suite let’s you change your brain state at the touch of a button.” okaaaayyyyy
I had to Google this, and as soon as the site page opened my Spidee Senses immediately went up. I don’t know if I would spend the money, even with my impulsiveness. They do list all the “famous” people with ADD/ADHD, but I think you could probably find all the information contained in that book right here on this site. I’ve got “Think & Grow Rich” right beside me on my bookshelf, and I didn’t even fiinish it. (That probably doesn’t surprise anyone here)

And them using the “DaVinci” word??? I don’t know …..
Anyone else?
