Long time skateboarder, hung up in a 9-5, knees are starting to shit the bed at 30, and don't skate much any more as a result. Realized, fairly recently, that over the years my mental state was declining/flatlining largely in part to not exercising. Skating is just fun, provides a sense of freedom, used to be a huge part of my social life, and the physical activity kept my body and mind in shape, and it's totally left a negative impact not having that involved in 50%+ of my daily activities.
Going on a tangent, but I recently purchased a recumbent bike as a means of remaining stimulated/keeping boredom at bay while exercising, and it's hands down one of the best purchases I've ever made. It's a matter of going to YouTube and popping on a walkthrough on a framework/library/etc, the news, documentary, or anything of interest, and just peddling away for the next hour... Only problem is, it's hard to stop going once you start :/
Anyways, read through this thread and your mentions, as someone else has mentioned, are the most articulate descriptions of the struggles that one faces with ADD. Personally, I'm in an environment where many don't consider it "real" and look down upon those who have sought medical help as "meth addicts", and my only wish is for them to understand and also to be able to distinguish the medications from one another and not group them with illicit/highly toxic drugs.
Glad to have come across yours and many other's comments on the topic. Made my morning :)
