@kaylinart, I appreciate this article. I have heard "Leave Enough Time for things" called buffer time. It is the empty space that you need to schedule for the things that you do not yet know that you needed to schedule.

Having just moved back the US, I find that I have to book a 15-30 minute appointment with someone about 2-3 in advance. What if there was a real emergency? What if my need should be addresses immediately? Not sure of the answer, but it seems that a lot of people don't have time for the little unexpected things that happen everyday.
