Now we can understand that the essence of leadership is force and it must have the three elements of the vector.

However, we have to know one more. It's about the proper leadership for the organization.

The appropriateness of leadership can be proved by ‘Newton’s second law of motion’. The formula is very famous.

Force is mass times acceleration. In leadership, leadership is the organizational size times the change of the organization.

Therefore, the change(a) is inversely proportional to the size(m). This is why it is difficult to change a large organization.

To achieve right change, large organizations require big leadership, small organizations require little leadership.

Large organizations don't move with little leadership. Big leadership in a small organization is too strong, so can make it broken.

​ Leadership is neither big nor little. You need the proper leadership for the size of your organization. And then you can get the right change!
