What does it take to really energize people and motivate them toward a goal?  Inspirational leadership might seem idiosyncratic and hard to quantify, but, according to Adam Galinsky, professor at Columbia Business School, it involves three key elements: having a vision, setting an example, and mentoring. His research shows this is true across industries and geographies, and he offers advice on how to improve in each area. He's author of the book Inspire: The Universal Path for Leading Yourself and Others as well as the HBR article “What Sets Inspirational Leaders Apart”.
