How does one become courageous or draw from courage?

You know, I wish I knew there was a formula for it.

I don't know.

I mean, it's funny.

People often ask, what was that moment, that defining moment that sparked you to make the decision to go from ordinary to extraordinary? I think I recently heard Oprah talk about she knew when her grandmother said, you need to put the clothes on the line.

You need to learn how to do that.

And she said, oh, no, I will never.

Which of these pivots scared you the most? And what did it teach you about your own potential?
