Any behaviour that has the effect of helping groups of people achieve something that the majority of the group are pleased with, and which we assess as significant and what they would not otherwise have achieved.Bendell & Little, 2015
Leadership. It may be a title, a position, a rank, an authority. The above definition, however, suggests that more than anything leadership is an action.
Using this lens, anyone can demonstrate acts of leadership in their day-to-day life.
Don’t get caught up in the title etc. Focus on the action which supports and enables others to do things they may not have otherwise done.
