Once upon a time, you thought you knew the answers to everything, and now you're not so sure. Welcome this uncertainty. It lets you know there's life in you yet. It lets you know you are making progress. Certainty may seem like progress to you, but certainty is more like an inn that you stay in for the night. Uncertainty, on the other hand, is your setting out on your journey. Uncertainty takes you places whereas certainty is a stopping-off place.
