Divine Logic vs Self Help Gurus

Rabbi Yaron Reuven says, Divine Logic is perfect and doesn't change, while human logic is flawed by nature. Many people will pay thousands or even tens of thousands of dollars to learn mussar from motivational speakers, but they ignore the Divine Logic of the Torah and the wisdom of the Jewish Sages that received this wisdom in an unbroken chain from Moshe Rabbeinu at Mount Sinai. Why would anyone choose to pay to learn from man when they can learn from HaShem for free?
