This post rings so true for me. I am hyper-efficient at getting tasks done, but I have to have exciting things in the pipeline and a compelling reason to finish them, or else I simply don't care.
So I really identify with what you said about the busier you are, the more productive you become.
For me, I try to spend as little time on a computer as possible, but ALL of my work is computer-based. So I've made it a game to try and get my work done as effectively as possible and "reward" myself with as much off-screen time as possible.
Great post!
