“Because happiness requires struggle. It grows from problems. Joy doesn’t just sprout out of the ground like daisies and rainbows. Real, serious, lifelong fulfillment and meaning have to be earned through the choosing and managing of our struggles. Whether you suffer from anxiety or loneliness or obsessive-compulsive disorder or a dickhead boss who ruins half of your waking hours every day, the solution lies in the acceptance and active engagement of that negative experience—not the avoidance of it, not the salvation from it.”
