Laura Vanderkam posted some excellent thoughts on making what little time we have more memorable.

Basically, time is elastic. When we decide that we need to do something, we find the time to do it. Other stuff either doesn’t happen, or it takes less time, or it gets punted forward. Much other stuff turns out to be more malleable than we might have imagined. And so, of course, the key to time management is treating the things we want to do with the urgency of the things we need to do. We make time for them first, and let everything else take the hit.
