Wouldn’t it be interesting to zoom backwards and forwards to other times and see how much time we really spend working and what areas we work in? Does email count? Checking Facebook? Answering colleagues’s emails? What counts? Does the work you do when you are tired count more than work when you are fresh? What do you do at your freshest time? Here is a thoughtful piece from someone who bothered to keep track. One point is clear and that is time away from work is crucial for efficient productivity.
Some time ago I was having a lot of trouble writing. So I kept track of exactly how much time I spent working on writing a particular paper. I quickly saw that it was so little time that it was no wonder the paper was not getting done. All I had to do was fix that and the paper got finished. So get to know yourself and be sure to leave for first the most important and the other things for later.
