Oliver Burkeman, author of the superb Four Thousand Weeks, commenting on our misguided attempts to hoard our experiences:

The truth, of course, is that experiences are for having, not for hoarding. As J. Jennifer Matthews puts it, in her book Radically Condensed Instructions for Being Just as You Are, “we cannot get anything out of life. There is no outside where we could take this thing to. There is no little pocket situated outside of life” to which you could take “life’s provisions and squirrel them away.” Spending your days trying to get experiences “under your belt”, in an effort to maximise your collection of experiences, or to feel more confident about the future supply of similar experiences, means placing yourself in a position from which you can never enjoy them fully, because there’s a different agenda at play.
