The best leaders I have had were also teachers and mentors. They were willing to allow me to ask question but allowed me to make mistakes because they knew I would learn more from them then if they gave me the answers. After time I needed new mentors and new responsibilities to grow into. Seek out the tough assignments, the worst jobs and learn how to solve problems. And make friends. Your peers can help you and you will need help as all leaders do.
Good luck! You will need that too!
