Uniterrupted time or rapid change of focus?
Recently I was reading a psychology book. I found somewhere in the book a statement that our psych system prefers to have stability and focus. It was said that we need an uninterruptable focus for at least 1 hour to feel not stressed. Now, my GTD system has 16 projects with 55 next actions. They are different and usually not to big (2 to 20 minutes). It assumes my psyche has to change the focus every 2 minutes. It makes me feel nervous. Plus if I follow the priority when choosing an action then I have to change contexts that doubles the stress.
Can we say that batching actions leads to more focused work? Do you batch calls, computer actions etc or follow the priority indespite of contexts? What's the best way to DO?
