Uncertainty also relieves us of our judgment of ourselves. Then we don’t know if we’re lovable or not; we don’t know how attractive we are; we don’t know how successful we could potentially become. The only way to achieve these things is to remain uncertain of them and be open to finding them out through experience. Uncertainty is the root of all progress and all growth. As the old adage goes, the man who believes he knows everything learns nothing. We cannot learn anything without first not knowing something.
