Think hard about what you have done today. Have you got everything you wanted to do done? How about things you didn't expect you would accomplish?
Extend that to, say, the week. What did you do? What didn't you do?
Now, maybe, your life. What do you really want out of your time here?
The purpose of this exercise in pretentious wankery was to have you evaluate your existence. We spend a flickering of time here and you must get the most of it. When I was a child, my parents shelled out a few bucks to take us to a fancy cafe for breakfast and I would have died if it weren't for the archaically-trained waiter executing the Heimlich Maneuver. I had completely forgotten about the experience until just the other day when a car, cruising through a red, clipped my backpack.
We don't have much time here. How do you make the most of it?
