Reflections on work: the first thing we do

When I get to the office I find the first thing I do is to go straight to my computer and fire it up to find out what it is telling me to do.

Why do I do this? Do I not know what I want to do for the day already?

I think I may be more effective if the first thing I do is something I had planned to do the night before, that did not involve a screen. Perhaps reading, or writing, or chatting with somebody. I wonder if I spent the first 15-30 mins of my day doing this whether I would have more ownership over my day.
