Your phone keeps every photo forever. Your brain keeps the ones you were actually there for.

A camera roll is not a memory. Photographing something while barely watching it leaves you a file and nothing else, because what your mind keeps is whatever your attention was actually on. The pictures you can still feel are the ones where you were in the moment first and reached for the phone second.

At the next good thing that happens, take one photo and then put the phone away for the rest of it. See how much of it you can describe a month later.
