We are bad at estimating and predicting. Our gut feeling is nothing more than a feeling. We have opinions and ideas that are, for the most part, pretty average. In almost every situation, there is at least someone else who is more prepared, more qualified, more worthy than we are. When we think we are giving advice, we are actually mostly telling others to do what we have not found the courage to do ourselves. We are different and unique, yet not necessarily better, more prepared, or smarter.
When we remain grounded, it is much easier to appreciate ourselves and others.
