" [I]f you put a wider lens on your life and subtract every day that you have experienced as stressful, you won’t find yourself with an ideal life. Instead, you’ll find yourself also subtracting the experiences that have helped you grow, the challenges you are most proud of, and the relationships that define you. You may have spared yourself some discomfort, but you will also have robbed yourself of some meaning. "
