The cost of being certain is high. You hear so much about the cost of being wrong. What if you invest in that and it fails? What if you move there and you don't like it? I know it sounds like a good job, but how can you be certain? You cannot be certain of anything, ask 120,000 laid off postal workers. If you do not take risks, you will never accomplish anything. That is certain. That means that waiting until you are certain will cost you your life; a meaningful one anyway. Zen Presence - minimalism, simplicity, self improvement, simple living, Zen in modern life.
