A little criticism makes me angry, and a little rejection makes me depressed. A little praise raises my spirits, and a little success excites me. It takes very little to raise me up or thrust me down. Often I am like a small boat on the ocean, completely at the mercy of its waves. All the time and energy I spend in keeping some kind of balance and preventing myself from being tipped over and drowning shows my life is mostly a struggle for survival: not a holy struggle, but an anxious struggle resulting from the mistaken idea that it is the world that defines me.
