I don't know if this course is cheating. The key is to change your husband's thinking. To tell the truth, people's life or management thinking (I don't know if your husband is a management position) can't be changed simply by listening to other people's inspirational stories or listening to others' blowing water. The key lies in their personal experience and level. For training institutions, it is just selling a course. They will not pay attention to the results of your lectures, nor will they pay attention to whether it will help you. Their role is to persuade you to pay for the lecture. From the perspective of commodities, we can fully understand this relationship.
Therefore, the key is to change your husband's mind. He is bewitched and bent on taking classes to change his destiny. You can wait for a while, and it will be fine after this time.
