Steve Pavlina on the concept of a time log:

I really admire this guy.

Here is the essence of Steve Pavlina's post on time and significance:

"The actor James Dean said, “Dream as if you’ll live forever, and live as if you’ll die tomorrow.” There are several popular variations on this quote, and they serve to remind us to pay attention to what we truly value. The finality of mortality endows reality with vitality.

"While it can be difficult to figure out what matters most to us even when considering that we might die tomorrow, perhaps it’s easier to notice what matters least. If you knew you’d die tomorrow, what wouldn’t you do? What activities would you definitely not include in your last 24 hours? Work? TV? Email? Web surfing? What people would you not spend even a moment of your last 24 hours with?

"How would you choose to experience your last day as a human being? Why not find out? Consider taking one day out of your life to have that experience now — perhaps an otherwise empty Saturday. Live that day from dawn til dusk as if it were your last. Feel every precious minute ticking by. What time would you get up? What would you eat for your last breakfast? Who would you spend time with? Where would you go? What would you do?

"If you actually take a day to run this experiment to see what you come up with, perhaps you’ll notice that there are things you would do during those last 24 hours that currently have too little presence in your daily life. Can you bring some of those things into your life right now even if you don’t expect to die tomorrow? Can you cut back on some of those things that would be irrelevant in your final days?"

This is the basic context for a time log, which is simply jotting down the time when you start and stop any activity for a week.
