Time is a tough one. For one thing, it's not really accurate to think about Time without also thinking about Space.

And thinking about Space/Time - really, really accurately thinking about them - isn't all that helpful, for most people. We get along very well with the roughest approximation of Space/Time, because that's all you really need in order to find your toothbrush; and because really, really accurately thinking about Space/Time leads to you giggle insanely while you hang from the overhead lamp and carry on a conversation with your chair.

Because we're not really equipped to deal with the utter and complete weirdness of Time.

My advice? Get one of these calendars. They draw tidy little boxes around increments of Time. That gives you the illusion that you've contained Time. Which, day by day, is what you actually need.
