And there are different degrees of ADD or ADHD.
I remember a friend I had for a short while in high school who, looking back on his behavior, was obviously an extremely ADHD person. Couldn't sit still, acted out frequently, was known to be a `trouble maker`. I would blame the acting out on ADHD. He was also a very talented artist, he could draw very detailed pictures, which had to take concentration and focus for hours.
A common misconception of people with ADD is that they can't focus, on anything. Which isn't true in my case - and I'd say I'm more mild to intermediate ADD. I have a had time focusing on things that aren't in *my* interests. Things that I'm fascinated by, or really want to do, I have no problem focusing on for hours. I soak them up without effort, because the intrigue me and I'm curious about them. For me, in my pre-drug years (and not diagnosed as ADD), I could draw for hours. I would have an idea in my head - a visual picture - and I could sit and draw until the image in my head was now on paper. I also was fascinated by computers, and computer programming. I taught myself how to program and would spend hours sitting at a computer typing code.
One thing that frustrated me was a girlfriend who was diagnosed as ADD and took adderall. But she would frequently not take responsibility for her actions, and blame everything on her ADD. `I have ADD.` `But, I have ADD.` `...I have ADD...`
It became her crutch to explain her action/inaction on ADD - and never seek solutions to her behavior.
