Interesting to read the experiences of others.

I experience difficulty with task switching. When I latch onto a problem, I feel like I cannot do anything else until that problem is solved. This makes for very inefficient studying as often I just need time to digest. This also creates problems for multi-tasking.

What I find strange is that I have much less of a task switching problem when it comes to programming.

As others have pointed out, will-power comes and goes with energy levels. On afternoons I'm practically useless. In my experience the disparity between what one wants to do and what one ends up doing is function of available energy, as a form of mental agility.
