Life at Zero

Ever since reading Getting Things Done: The Art of Stress-Free Productivity, I've been really focused on Getting to Zero -- i.e., managing my tasks, projects, life by concentrating on the next concrete Action I can take, taking it, and then, being at rest.
Fundamentally, for me Zero means having an empty head. It feels weird to me to write those words, me who loves thinking and doing and making shit happen, but seriously,
having an empty head is totally my goal.
