lead·er·ship - /ˈlēdərˌSHip/ - the action of leading a group of people or an organization.
I believe the definition above lacks depth and clarity. A more expanded definition is that leadership is the art of motivating a group of people to act toward achieving a common goal. In a business, this means directing colleagues with a strategy to meet the company's needs by inspiring and communicating an idea. This requires communication to others in a way that engages them enough to act as the leader wants them to act. Put even more simply, the leader is the inspiration for and director of the action. They are the person in the group that possesses the combination of personality and leadership skills to make others want to follow their direction.
This is, of course, predetermined by surrounding yourself with the right people. For me, I see my role as a leader to inspire others to be the best version of themselves and therefore, drive towards a common goal. In the three companies I play leadership roles in, I do what I do best so that others can do what they do best. I have the vision, passion, and acumen to know what it takes to make a business thrive. This acumen has been developed through both success and hardship in business. Although some may call it 'failure,' I see it as learning.
