When we consider that each of us has an element of free will to decide what to do, then resigning to leave the world just as it is, with all the craziness happening, without at least putting effort to change it for the better totally misses the point of what it is to be here. I miss the days when life was simple, even though I can't remember much of those days in a a conscious way lol.
I think there are memories that stick with us long after the experience has gone to maybe remind us that we have the power to replicate those experiences, one way or another :)
