A birthday is perhaps the most appropriate time to reflect on time passed. It invites thought about a year of one’s life in its entirety, and comparison of that year to others. It can allow a deeper understanding of how we’re spending the only thing we really have—time—and whether we’re spending it the way we want to be.
But to reflect on a year of life is no easy task, and it is made more difficult by the reality that more recent events take on larger significance in the mind’s eye. Those events that happened 364 days ago may well have been the more consequential, but those that happened yesterday bear greater significance in how we’re immediately living life today.
The challenge is to attempt, as best one can, to get rid of the importance adjustments our minds make, and assess the events of a year without the effects of presentism. The only way I know to do this is through keeping a diary every day of the year.
A diary removes the presentist bias by showing what we thought of things as they occurred, and how we judged their importance at the time. It treats every day as equal, but allowed us at the time to make judgements of importance. When reading back over a year on a certain day, like a birthday, one can then see events as they were and how they affected one at the time.
A birthday can become hard work. Looking back over 365 days takes time, and especially when it comes to the reality of your life, it takes energy. But it’s a necessary excuse to take that time, and to spend that energy, to look back on how we’re spending our days.
For if how we spend our days is how we live our lives, and we wish to reflect on how we’re living our lives, we better record how we spend our days, and at some point we better make some sense of all that time.
The irony is that the presentist bias may be precisely what gets in the way of keeping a diary, by telling us that today is just too busy, or too important, or something or other, and that’s why we can’t write about it. Reflection takes time, every single day.
