I am actually laughing out loud right now!! The post from Shirokuma could have come directly from me. Did this..got bored…I have done many different things and did them well BUT got bored. To me doing the same thing for many years like many many people so actually sounds painful. I just could not do it. Right now I am in the process of becoming.. yep a FIREFIGHTER. I have been drawn to this for years and decided to do it. Maybe it is all the action and excitement. I wonder how many firefighters have ADHD. Your not alone with obsessions. Sometimes I think it is just to keep my mind as bust as possible. Good luck with your challenge.
