All the variety, all the charm, all the beauty of life are made up of light and shade.

Leo Tolstoy

In his classic 1878 novel “Anna Karenina,” Leo Tolstoy reminds the reader that there are always ups and downs in life, and that expecting perfection will inevitably lead to disappointment. Things are not black and white, but messy shades of gray. Once we can accept the nuance and complexity of our existence, we can come to appreciate the good while taking the difficult in stride.
