“One of the capabilities, which seems to be the most difficult for aspiring leaders to maste is realistic optimism. It requires one to recognize that our experience of life is largely up to us, that our situations, good or bad, are largely due to our ability on a moment-to-moment basis to capitalize on opportunity. Those that approach life as if it is largely outside of their own control, or that others are largely to blame for their circumstances, generally find growth elusive.”
