It's hard to change habits, but a gentle push can move us in the right direction. This episode, TED speakers offer deceptively simple "nudges" for managing our kids, our health, and our aspirations. Guests include behavioral economist Richard Thaler, psychiatrist Judson Brewer, psychologist Carol Dweck, Girls Who Code founder Reshma Saujani, and economist Sendhil Mullainathan.
