A mind that won’t switch off can make a normal life feel heavy. In this episode of Ten Mentors, Dan shares why he read Dale Carnegie’s How to Stop Worrying and Start Living—and the six practical lessons that changed how he handles stress in real life: defining the worst-case scenario, sealing the day, putting a stop-loss on spirals (especially about people), letting the past stay in the past, using probability instead of panic, and closing the loops that keep anxiety alive. Along the way, Dan connects Carnegie’s tools to thinkers like Eckhart Tolle, the Stoics, Buddhism, Nietzsche, and Aristotle—different language, same message: stop feeding worry with your life.
