We cannot get back to the past that we once knew cuz that would undo all the progress we've made.
Life's not like a video game. We don't get to redo, no replaying going through old levels that we want to.
So, if it's just one shot one life that we're given, one moment to live in this game we're playing. Then it's not about winning. It's not about losing. It's not about gaining another day.
I won't see you after I die but you can always stop by and read what I write.
