“The foundation of courage is vulnerability--the ability to navigate uncertainty, risk, and emotional exposure. It takes courage to open ourselves up to joy...joy is probably the most vulnerable emotion we experience. We’re afraid that if we allow ourselves to feel lit, we’ll get blindsided by disaster or disappointment. That’s why in moments of real joy, many of us dress-rehearse tragedy...I call it foreboding joy. The only way to combat foreboding joy is gratitude.”
