I have mentioned way too many times on Always Standing that I love to learn, so much that a single link to a post exemplifying this wouldn't be enough - I say it all the time, because I mean it. I just read an article that ties this to my ADHD, and I totally agree:
"We need to be careful about what we label as a disorder. When it comes to ADHD, for instance, there is growing evidence that ADHD individuals achieve very good outcomes by normal social standards. The popular-culture stereotype is of an ADHD (often "ADD") person superficially clicking from one channel or Web site to the next. An alternative vision is that many ADHD individuals adapt and end up using their cognitive profile to propel themselves from learning one piece of information to the next, and in fact end up better educated and maybe better situated to deal with the social world as well."
