One symptom of ADDADHD is hyper focusing . So while we are often bombarded with conflicting thoughts , sometimes a subject or activity can block those out and instead we hyper focus on that thing . As for the suggestions on how to improve concentration , my advice is to become more in tuned with your body ' s natural cycles . There are going to be times when your energy level is higher or lower . A time when you are feeling extremely fidgety is not a good time to read . I took drugs for a few years but felt like the Ritalin was changing my brain and energy levels . So now I try to plan my day out based on how my body is functioning . It helps . <| sep |> Damn this Rover is still kicking . That ' s awesome . <| sep |> True . Sorry about that . lol .
