" I learned to look more upon the bright side of my condition, and less upon the dark side, and to consider what I enjoyed rather than what I wanted; and this gave me sometimes such secret comforts, that I cannot express them; and which I take notice of here, to put those discontented people in mind of it, who cannot enjoy comfortably what God has given them, because they see and covet something that He has not given them. All our discontents about what we want appeared to me to spring from the want of thankfulness for what we have. "
― Daniel Defoe , Robinson Crusoe (Robinson Crusoe, #1)
