As women, there is so much we can learn from one another. Each year, Marie Claire hosts the Power Trip conference—an event designed to empower and connect influential women from all kinds of industries. We teamed up with Stitch Fix to ask the successful leaders in attendance this year, including the brand's founder and CEO Katrina Lake, what mantra has been most meaningful to them in their professional journeys. Lake shared her mantra of allowing herself to believe in what's possible, a mindset that's helped her become the youngest woman to take a company public and be vocal about causes like parity in parental leave. Check out the video above to hear mantras from other female founders, CEOs, and directors that reflect what they've learned, how they've overcome obstacles, and the ways they stay motivated and passionate. Some of our favorites: "Gratitude is a superpower." "There are no mistakes, only experiences—and it's what we do with those experiences that shape the fulfillment and fullness that we feel in life." "None of us knows what will happen in our lives, but if you work hard and you're kind, amazing things will happen." Consider this your daily dose of career—and life—inspiration.
