Derek Sivers asks, “Shouldn’t our personal markers and celebrations happen at personally meaningful times?” Time is personal.
@vasta @patrickrhone Agreed. I tend to think of it this way: in most cases, the most significant moments are not coordinated worldwide on a schedule. In fact, they tend to be unpredictable; sure, the start of the school year is scheduled but your first day isn't necessarily the day when it clicks into place; yes, you have a deadline for your project but it might take days -- or even months! -- before the impact of that deadline is truly felt.
@simonwoods @vasta This is one reason why I keep a Daily Log as well as a calendar. The calendar is for the things I intend to do (meetings, tasks, events). The Daily Log is where I record the things I actually did and note important things that were/are not on my calendar. Many thoughts/moments/events end up in the log that were not planned or things that “just happened".
Because of this habit, I can recall the important details of any day in the past 15 years or so. I can even tell you how I slept the night before for the past five (when I began tracking that).
(FWIW: I use a Hobonichi Techo for my Daily Log).
