Who was the best leader you ever had?

I once had this project to deliver while taking my bachelor degree and we were a group of 4. One of the girls just assumed leadership, she was the best student of the class, she divided the project in various tasks and distributed them to the people of the group. She didn’t give any task to herself, instead she would check with everyone on their tasks and help whenever people needed to. One of the guys was having trouble with another class and so he didn’t do his task, instead of yelling or getting mad she helped him with the class that was giving him trouble until the problem was gone and then he was free to the task. She also constantly checked our availability and scheduled weekly meetings for us to take our doubts in the project and to always check its evolution. She was always on top of the project and was always making sure we did our part but she never berated us if we hadn’t done our part. Even though she was the best student and she assumed a leadership position I never felt inferior to her because she never saw like that, we were just colleagues in her eyes but I did see her as our leader.
