There’s something about the change in surroundings that seems to make it easier to quiet down whatever gears are still spinning from the last activity and re-focus on a new task.
If I had my ideal work day, I’d sit in a coffee shop to brainstorm. There’s something about the commotion and the coffee that inspires creativity.
I’d stand up to do rote tasks like read through and answer email. Standing helps to stay awake.
I’d only sit when I really need to focus and nail down a presentation or solve a problem.
A simple change in environment increases productivity and awareness. After all, you should be able to work from anywhere.
