I generally have difficulties in keep my attention up during lessons, meetings or any kind of formal gathering where someone is talking. Unless it is extremely interesting. But also in that case I need some help. What I’ve always been doing is to scribble, sketch and write. It just helps. To someone external observer it just seems I’m minding my own business but in reality it is only when I have pen and paper that I’m listening. One of preferred subjects have always been forms and blocks. Here my high-school and univerity years more recurring them on steroids, renewed and improved. Ps. No, I didn’t have ADHD growing up. I just get bored really, really fast.
