In 2013, I was on a phone call with the editorial team at one of the biggest publishers in the world, fielding questions about how I planned to structure a book I had no idea how to write. I was a full-time psychotherapist who'd written a viral article that led to this meeting.As I fumbled through a few answers, I caught myself thinking, Don't say anything stupid. Don't blow this opportunity.I knew that thinking about all the ways I might mess up would likely cause me to mess up. So I took a deep breath and ran the best mental strength play I could in that moment — I activated my power phrase and told myself, I'm a strong, straightforward communicator.Repeating that phrase in my mind helped me field the next round of questions with a bit more poise. I shared my story, acknowledged I hadn't had much time to think about how to turn my ideas into a book, and assured them I was a hard worker and eager to learn.Not long after that call, they made me an offer, and I signed my first book deal.The two-minute reset is a way to stay mentally strongActivating my power phrase was the two-minute mental reset that helped me land the book deal opportunity, and it's one of 50 tools for high-stakes situations I cover in my new book, "The Mental Strength Playbook."Think about the last salary negotiation where you took the first number on the table or your performance review where you blanked on half of what you meant to say. Those are the moments a power phrase is built for.
