Humility and competence are the keys to a successful life.
Humility breeds competence, because it leaves a person in a state of constant wonder and curiosity regarding what isn’t yet known, thus motivating the person to learn and increase their skills. Competence leads to practical success for obvious reasons, but it also can result in arrogance and isolation. Cultivation of humility prevents this from happening. Being a success, in the limited sense of the word, is not enough. Leading a successful life is.
