If you're a student body president, team captain, section editor for the school newspaper, or in any other role where your job is to supervise or lead people, here are three great books to learn the skills you need to be great at it.
The One Thing You Need to Know by Marcus Buckingham
Leadership and management are not the same thing. They require very different kinds of skills, and Buckingham explains how to do both. He's also got a surprisingly simple secret for personal success that involves quitting. It's a good read.
to Great by Jim Collins
Collins is a professor at Stanford Business School who based this book on his exhaustive study of great companies and the leaders behind them. Some of the findings are surprising, like the fact that charisma can be as much a liability as an asset for a leader, and that spending time and energy trying to motivate people is a waste of effort–if you have the right people, they will be motivated as long as you don't de-motivate them.
First Break All The Rules by Marcus Buckingham and Curt Coffman
The authors worked for The Gallup Organization and did a comprehensive study to find out what great managers do differently. If you're in any kind of supervisory role, this book will give you great ideas about how to manage the group and get the best out of each person. Every single adult I know has a story about working for a terrible manager, but you can start learning to be a great one while you're still in high school
