Stanford University President Marc Tessier-Lavigne talks about ways to quench a desire to make a social impact in the world. Bring a “spirit of service” to whatever you do, and appreciate that any form of work can be mission driven and contribute to solutions, he says. He also suggests volunteering as time permits or committing to a cause completely at some point in the future. “Life is long and lived in chapters,” Tessier-Lavigne explains.
