I don't know if I have ADD / ADHD; but I find it hard to concentrate for a long time. I think the biggest thing I did was accepting that I suck at dealing with distractions and don't have much willpower when dealing with them. So - I put in artificial barriers in my environment. I keep my room and desk clean so there's nothing to distract me. I installed LeechBlock on Firefox to block twitter, facebook, and all the other sites that distract me for the whole day except 8-10 pm (I should do this on my office computer too!). Every night - I make a list of what I need to get done and the next day I write down if I was productive or not. All in all, cultivating the awareness that I suck at time management and inserting artificial barriers in my environment has helped me a lot! Good Luck!
