People often underestimate the power of... Passion. I see it in my own work. I hear, "She's not a doctor; she doesn't know what she's talking about." But I don't need anyone else to give me answers—determination keeps me moving forward.
I felt most powerful when... My mother died in my arms. Death is mysterious and frightening, but I had the strength to help my mother through it. I'm proud of that.
A true sign of power is... Self-assurance. It's a struggle, but that confidence comes from being comfortable with yourself and the decisions you've made in life.
