It is easy to say I am thankful for the sweet and beautiful things in life: flower gardens, ice cream cones, diamond rings, dances under moonlight, children’s laughter, birdsongs, and the like. The challenge is recognizing things of value in the dark, sour, uglier parts of life. But if you look hard enough, you will find that even tough times offer pearls worthy of gratitude.
