''The ability to *hyper-focus* (without stimulant medications)
is one of the distinguishing traits of ADD or ADHD.''
''It tends to be a very enjoyable state of mind, losing yourself
in some enjoyable activity so to speak.''
*That* was the missing piece of the puzzle for me. Yes, your
friend Kenny is DEFINITELY ADD/ADHD - All of the other stuff
about being unable to focus is all true but I always wondered
about my ''obsessiveness'' - how I'd get COMPLETELY wrapped up
in a project or task - THOROUGHLY enjoying the heck out of it.
*Hyper-Focus* - That was the missing key. Yup. Now I feel
better. I am part of a club. :P
