Here's another idea: Instead of getting good at context-switching, are there ways to set up your life so you get to stay focused (and still pay the rent)?
Well, obviously there are. I had that when I was an employee a few times. A friend of mine is studying organ in a master's program. She practices organ 2-4 hours a day, early every morning. She spends a month or two (or more) getting good at a really hard piece, really getting to know it, mastering it. I envy the day-to-day continuity that she has. Other stuff during the day is OK, like easy classes, but not something else that occupies the subconscious "workspace".
Could that day-to-day continuity be achieved in a scientific/mathematical grad program? In a solo business?
