Being a leader is to incorporate what you believe into the company vision and mission. Sometimes, what you want and what the company wants could be different. But you need to do your best to put them together. To this end, you need to develop your character so that people can look up to and do their best to follow you. You need integrity, credibility, and value differences.
"Integrity is the consistency between what you say, what you do, what you value, and what your organization values."
