I used to try stacking the deck in the way this article mentions, until I tried Adderall and realized that it made this kind of task juggling totally unnecessary.

It was really bizarre to experience. However, to be honest, I don't need laser focus most the time, and like the sort ambling approach he discusses. My strategy for the next few months is going to be using it one day a week, for sweeping up the boring things (that otherwise haunt my waking life).
