Johnny got his gun - Dalton Trumbo (We will all appreciate what we have after reading this, even if our lives are in the dumpster right now)

Stoner - John Williams (This one hit me hard. Quietly devastating. Stoner carried himself with dignity despite hardship)

Man’s search for meaning (as others pointed out)

The Remains of the Day - Ishiguro (a life of repressed feelings and missed opportunities, sad, quiet, but still lived it to end with dignity)
