“You have to stop thinking about yourself and focus more on other people and the team.”

“Leader” does not mean that you are the Leader when someone reports to you in the system, nor does it mean that you are the Leader automatically when someone reports to you in the system. From the perspective of a company, “Leader” refers to someone who is willing to follow you for a specific business goal, so he can be called a Leader. The so-called “technical leader” refers to a person who has expertise in technology and is willing to follow you to achieve business goals.
