Wisdom means “knowing what you know and knowing what you don’t know.”
Behaving with an attitude of wisdom means that you act on your present knowledge while doubting what you know. It means that you do things now, as you keep learning along the way. It means that you compensate for your limited knowledge by building on old ideas and joining communities of smart people rather than relying only on your own insights.
Unacknowledged ignorance and arrogance stems from an absence of wisdom.
