The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run. – Henry David Thoreau

Life is the game that must be played. – Edwin Arlington Robinson

What is life? It is the flash of a firefly in the night. It is the breath of a buffalo in the wintertime. It is the little shadow which runs across the grass and loses itself in the sunset. – Crowfoot, 1890, as quoted in Catch the Whisper of the Wind compiled by Cheewa Ja
