I hope my answer is not too late. I have ADHD and basically its all about finding the right tools. I still tend to stay out of focus when doing things but i have learn from “conditioning.”
I agree with Andrews’ response that, Environment does play a fact in trying to be in focus. Connecting his response to my scenario, I couldn’t deal with too much clutter in my work area. I tend to “split” my attention if those things are in sight.
For example: stacks of different paper works under different areas of study. What i do is that i just keep whatever I need, the book, the highlighter and pencil, anything else, stays somewhere else.
I also keep my Blackberry away from me when working, the constant emails, IM, text message and calls are major distraction. This also works with the laptop, i stay away from it, or better yet, turn off the wi-fi so i can basically not get IM and just turn it on when needed.
In conjunction with the “environment”. I pick where I have to study. I have learned that my study room in my house isn’t really the best place to be at. I have the people around me who can basically come in and stop me. I try to be at the campus’ library and be in the most isolated place just so that i can focus. Seriously, people in general puts me off track. Why? Because i notice weird actions, things their doing, and basically some other talks i can overhear.
There are more things i think that can really help to ease yourself up and be able to focus. Before i get ready to study or write a long term paper, I try to make sure I have completed other tasks before hand in order for me to basically say “Oh snap! I forgot to….”
Lets also not forget other factors, stress levels? other tasks? hunger? lol.
Before i prep myself for studying i usually get a good work out before that, good relaxation and get ready for something big like studying.
Anyway, i can keep on going but, i think this can branch out to somewhere else. This things basically work for me, and i cant tell how you would react on this. I know we all do it differently but I just want to share what I think and hopefully make things easier for others as well, I know how crazy it can be folks. Hang tight we can do it :)
