In the beginning I felt awkward with nothing on my wrist. But, the benefits were immediate. I'd be in a meeting and could really focus on the agenda and what was being said (or not said) with a feeling of being ungoverned by the constraints of time. I ceased tracking time and thinking of an exit strategy to get into the next meeting.
Then I discovered that almost everything, from a credit card receipt to taxi meters displays the time. I think it's a conspiracy.
