''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

  Anybody else in the ADD/ADHD club?
