Your future is becoming your past faster than you realize.

The distance between anticipating something and remembering it is much shorter than it feels. The event you have been thinking about for months takes an afternoon and then belongs to the past permanently. Most of life is spent looking forward or looking back, with the actual moment passing through quickly and largely unattended. That is simply how the arrangement works.

When something you have been waiting for arrives, try being present for the thing itself rather than for how it is going. Put the phone down for part of it. The moment is short and you are the only one who can attend it.
