Erin there is no doubt in my mind that leadership is more than just leading an organization. You are correct that leaders emerge in different settings, under different conditions, and display different traits.

Does being put on the spot to "perform leadership functions" bring an added perspective to it? Surely of course.  Yet doing it does not completely define it anymore than researching and exploring it.

Leadership is complex and situational.  It has many dimensions and leaders come in all types.  Green Berets for example lead with a certain focus, mindset, and in many cases produce amazing results. Likewise, a young entrepreneur who might not be able to lead a green beret cause can inspire other young workers and lead them to bring a product to market that rivals the largest corporations.  Teachers lead  us by spotting talents and inspiring growth.

Those who define greatness only by what they know and do show the weakness in their logic.
