Ten years ago, I still feared loss enough to abandon myself in order to keep things stable. I'd smile when I was sad, pretend to like people who appalled me. What I now know is that losses aren't cataclysmic if they teach the heart and soul their natural cycle of breaking and healing.
Life is full of tough decisions, and nothing makes them easy. But the worst ones are really your personal koans, and tormenting ambivalence is just the sense of satori rising. Try, trust, try, and trust again, and eventually you'll feel your mind change its focus to a new level of understanding.
Cheerfully fessing up to our failures turns crazy mind off, humility and compassion on. I learned this in a karate dojo that had a strange tradition. Everyone there loved recounting failure stories, and after an evening of smacking one another, we'd sit and have a beer while the students swapped tales of martial arts disaster.
