@fmf saidMy sympathies. I'm retired now and more scattered than when I was working. Maybe because working to support oneself involves some degree of fear and the adrenaline helps with focus?
I have some difficulty managing my distractions.
I also think that the internet and the info flood exacerbate any ADD tendencies.
How about some kind of daily meditation to develop detachment from attentional snares as well as selective focus? I know it might seem like a waste of time, but think of it as developing your mental fascia.
