"When I was in college, I went off to the mountains for a weekend of hiking with an older, wiser friend of twenty-two. After setting up our tent, we sat by a stream, watching the water swirl around rocks, talking about our lives. At one point she described how she was learning to be “her own best friend.” A wave of sadness came over me, and I broke down sobbing. I was the furthest thing from my own best friend. I was continually harassed by an inner judge who was merciless, nit-picking, demanding, always on the job. My guiding assumption was, “Something is fundamentally wrong with me,” as I struggled to control and fix what felt like a basically flawed self."
