The more business a man has to do, the more he is able to accomplish, for he learns to economize his time.While I disavow Hale's views on rape, I've gotta give it to the guy: this quote is perfect for somebody with ADHD.
--Sir Matthew Hale
I have found many times in my life that the more responsibilities I have, the more I'm able to accomplish. I'm not exactly sure why this works for me. Maybe it's because the more there is to do, the more frequently one experiences the adrenaline of an impending deadline.
Whatever the case, I find that loading my days with blocks of time devoted to many different activities provides me with the ability to focus on more things for more time. It seems a little counter-intuitive to me at times--it would seem that someone unable to focus would do better with more time to do the things that need to be done. But I can't deny it: when my schedule is chock-full, it invigorates my mind and I'm actually able to focus more than when I have gobs of time.
Conversely, if ever I have a full, empty day, and only a few projects to do in that day, you can pretty much guarantee that I will not finish any of them.
So, thanks Sir Hale. In this thing, you have given good advice. (Too bad many abusive husbands have been vindicated by your ridiculous views.)
