The thing is, you're not even still you. The You that was you back then is long gone, just like the cameras and houses and friends you knew. Every moment is unique and time is a stream in which we all swim. Just do what brings you joy today and know that it will bring you joy in reflection years from now, too. Meanwhile, I just bought a bunch of film today to shoot through the Pentax ME Super I recently got for $40 at a flea market, so what do I know?
