1. Ken Robinson: How Schools Kill Creativity

Children are naturally creative, right up until we educate the raw spark of wonder out of them.

He invites educators to encourage kids to dance, experiment and make mistakes.

2. Amy Cuddy: Your Body Language Shapes Who You Are

The social scientist, who kicks off her speech with a “free no-tech life hack” that will probably turn your frown upside down, says our body language speaks loud and clear to those around us. And it might just have a lot to do with our success. One thing’s for sure: You’ll walk a little taller and sit up a little straighter after you take Cuddy’s 20-minute “power posing” crash course.

3. Simon Sinek: How Great Leaders Inspire Action

Extolling the trailblazing, renegade spirit of iconic historical figures like Martin Luther King, Jr. and the Wright brothers, ethnographer Simon Sinek dares people be rebels, to “think, act and communicate” in ways that are “the complete opposite of everyone else.” In his talk, the author of the motivational classic Start With Why (Portfolio Trade, 2011) describes what he calls the “golden circle.” It’s a means of communicating “from the outside in,” a way to passionately talk about what you care about and believe. He says Apple does it — obviously to great success — and your company can, too.

4. Brené Brown: The Power of Vulnerability

Humiliation, embarrassment and shame are the fields of study that Brené Brown specializes in. Not many people talk openly about thosekinds of feelings, let alone in front of thousands. In her touching, often funny speech, the University of Houston research professor and author of five bestselling self-empowerment books, reminds us to be true to ourselves. How? By embracing our imperfections, something society pressures us not to do, at home and at work. Instead, Brown asks you to be you, to be real and really vulnerable. When you are, you’re kinder to yourself and to others. It’s not easy, but once you accept who you are — not who you think should be — flaws and all, Brown says you’ll connect with others in deeper, more meaningful ways. And P.S. — Stop beating yourself up already. You are enough.

5. Jill Bolte Taylor: My Stroke of Insight

When Harvard-trained brain researcher Dr. Jill Bolte says she had a stroke of insight, she means it literally. One morning, at the age of 37, she suffered a devastating cerebrovascular accident. A blood vessel in her brain suddenly burst. She could only speak “like a Golden Retriever” when calling for help. Her right arm “went totally paralyzed” and her world came crashing down.

You won’t believe Taylor’s first thoughts upon realizing she was suffering a stroke: “Wow! This is so cool! How many brain scientists have the opportunity to study their own brain from the inside out?” Amazing, right?

In her deeply personal talk, Taylor pulls us into her eight-year recovery journey. She describes learning to walk, talk and think again — from scratch. And, of course, she also reveals her biggest “stroke of insight” as a brain hemorrhage survivor. It’s simple but so complex: our right minds can be gateways to nirvana, but only if we choose to step out of them.
