There’s no end to the catalogue of ways humans suffer, and manage to inflict suffering: illness and injury, psychic suffering, material deprivation, heartache, loneliness, catastrophe, separation, history, bad luck.

Consider for a moment the possibility that our very selves—our centred, internal, ever-present cluster of backstories we identify with the letter I—comprise as much everything we haven’t done as everything we’ve done. Everyone we haven’t become as much as who it is we find we have. Can anything useful be gleaned from the premise?
