Because this kind of learning goes on largely in a deep zone of the brain outside the reach of words (in the basal ganglia, a primitive part of the brain atop the spinal cord), leaders need to learn to trust their intuitive sense to access their life wisdom.
This is also why books can only teach you so much. We know a lot more than we can articulate. In common vernacular, this is called "experience". Also relates to my recent rants about quantitative metrics/measurements wrt decision making - if you base your decisions solely on metrics, then you're limited by what you can articulate.
