Mark Rober spent years trying to land a rover on Mars. Now, the former NASA engineer turned science YouTuber with millions of subscribers is launching a new mission: to teach the next generation of big problem solvers.

We are wired for connection, and yet many of us spend most of our lives avoiding it, says behavioral scientist Nicholas Epley. Drawing on decades of research into happiness, loneliness and well-being, he reveals why we consistently underestimate how receptive others are to connecting — and invites us to seize the small moments that lead to a more social life.
