If we define leadership as something others voluntarily want to follow because a leader inspire and communicates a vision and mission in a way that you want to follow in word and deed without obligation and are motivated by how many leaders are there so within your organization? I would guess not many and in some cases none.
While management is focused on tasks, leadership is focused on the person. All in all, the best leadership drives change and long lasting motivation.
Do you wonder why management often fails?
PS! I’m not saying we don’t need management, but without Leadership, management has no motivation or goal.
