This author views the relationship between leadership, learning, and service as being like spokes on a wheel. They are interconnected, and, therefore, move along together on a journey. When one of these spokes, these facets, is on the move, the other two accompany it for the ride. He believes that one cannot have one of these - call them what we may: activities, events, ideals - without the other two being present.
The driving force behind the journey, the one facet providing significant support to the other two, is learning. Learning is behind it all. When one is continuously learning, one is compelled to share the insights gained with others, thereby fulfilling leadership and service. The leadership and service components, then, are naturally attained because the insights being gained by the individual, which in turn are then dispersed out to others, are helping those others in some sort of meaningful way, either personally or professionally. For, what is the point in one's desire to be in a continuous state of learning, embarked on an ongoing journey of discovery and adventure, without sharing that knowledge and wisdom with others, thereby lifting them up in some sort of impactful way? How is it even possible to avoid doing so? This author cannot think of a logical explanation.
Even when the learner may not consciously be aware at any given moment in time of what his or her discoveries may mean in terms of service and leadership to others - he or she may solely be focused on his or her own career advancement or some sort of other personal gain at that moment - what is being learned, nonetheless, is still helping others along the way as he or she strives to climb higher on the latter of personal success. This arguably holds especially true today, in such an intertwined global community, workplace, and economy. That being said, learning for personal gain is compatible with learning for the benefit of others, and vice-versa, and leadership and service are not possible without the presence of learning. Therefore, anyone who has the capacity to learn has the potential to be a leader to at least some degree.
