Be Fearless posits that radical changes are more effective than small enhancements and urges us to be bold in trying to make progress.

As the first female Chairman of the National Geographic Society and one of the first members of the America Online team, Jean Case has been a change-maker for years.

Most notably, she and her husband established the Case Foundation, which exists to invest in world-changing people and ideas.

Case believes we need brave people who dare to try and solve the world's problems. That's why she wrote Be Fearless: 5 Principles for a Life of Breakthroughs and Purpose.

Case says that daring to go big can bring greater results than a cautious and conservative approach.

At her foundation, the team analyzed many game changers' lives to extract patterns of traits and behaviors. They discovered that, contrary to what most people think, you don't need to be rich or privileged to be a trailblazer.

Instead, innovators have other common traits. They go out of their comfort zone to make fearless promises with a high risk of failure, then work hard to stick to those commitments.

If they don't succeed, they learn from their mistakes and try again.
