Four failure modes of Hacker Schoolers

A very insightful post. I'm not a Hacker Schooler, but I find myself afflicted by these "failure modes" at various times. I can especially identify with the "too much task-switching" problem. I'm often unable to identify my priority, and when I thought I would just pick something to learn out of a list of things that seem interesting/valuable, I'd have doubt about my choice almost immediately. I wonder what the solution to this would be?
