Finding a role model to emulate is a grand way to become a better leader. But for my money, I would encourage you to find an anti-model instead. A leader you don’t want to resemble in any way.
First off, they are much easier to find than role models. Secondly, you will learn more from them about what not to do, how not to make people feel, and what messages not to send.
Their wisdom — or lack of it — will serve you for years as you develop your own leadership style and become the leader others want and need you to be. Role models are good teachers, but anti-models teach you how to evolve and what not to become.
