You took fifty photos at the concert and remember the one song you didn’t film.

Recording and experiencing compete for the same attention. Pointing a phone at something puts you slightly outside it, managing a frame rather than being in the room, which is why the one you left alone is the one that stayed. Footage mostly gets watched once, and the memory keeps working for years.

At the next thing you care about, record one song and then put the phone away. Decide which one before it starts, so you are not negotiating with yourself the whole way through.
