I don't necessarily disagree, but I think there's another way of seeing this here that goes: if some of your time is already accounted for by certain tasks, trying to regiment them out further ends up reinforcing the idea that you're losing time constantly. Scheduling out personal time in the same manner as working time pushes you to think about them in relative terms.

As a disclaimer, this is something I go back and forth on and I do tend to use time blocking myself because otherwise I find it hard to maintain direction over long periods of time.
