Short YouTube clip in which Donald Burns argues that a key red flag in a coach is that they do not have a coach themselves; he states such a coach is stagnant, effectively a fraud, and will not help a client grow.
If someone offers to coach you and they don't have a coach themselves, and you need to run fast. Why? Because it means that they're not growing. It means that they're stagnant. And if they're stagnant, guess what? You're going to be stuck right there with them. A coach who doesn't have a coach is a fraud. And if they're not investing in their own growth, what are you going to do to help and how they're going to help you grow?
If your restaurant only works because you work 80 hours a week, it doesn't work.
