In this video, Sarah Robb O’Hagan discusses some of the experiences and revelations that she had while working on her book,  Extreme You. Among the most impactful realizations is how many of the most amazingly successful people who, having achieved the “pinnacle” of a field (such as getting an Olympic gold medal), are never truly satisfied. Instead, they’re eager to overcome the next big limit or beat the next goal.

She also talks about the importance of not being afraid to try different things and fail until you find success—and how those early failures can sometimes prove to be the fuel that contributes to eventual success.
