From his early days playing music at weddings and parities, Marco Davis learned about the art and science of being an effective DJ. As he explains in this reflection from the 2009 Gathering, the science of DJ-ing is teachable; it involves understanding the structure of music and how the equipment works. But the art of being a DJ is much more difficult to master. Those who excel in the art know what to play next—they can read the crowd and engage them.

Davis believes there's also an art and science to social entrepreneurship. The science aspect is typically the subject matter of academic books and journals. And the art? It's about understanding people, awakening their passions, and inspiring them to follow their dreams. Social entrepreneurs who master the art ignite a spark that transforms people and makes them willing to risk everything to achieve their mission. In short, he says, they in turn become social entrepreneurs themselves.
