In today’s episode, Dr. Killeen shares a hard truth—mistakes aren’t the best teacher, they’re just the most expensive. While learning from your own errors has value, why not learn from others and save yourself time, money, and frustration? Successful people know the power of vicarious learning through mentors, books, and systems that shortcut their path to success. Dr. Killeen uses the analogy of climbing Mt. Everest with or without a guide to explain how mentorship can help you cut corners and speed up your journey without sacrificing the lessons.
