This is not about your ego. The wisdom and knowing that needs your loyalty is your intuitive awareness, the 'gut feeling,' which hopefullly you have learned to trust and rely on.
We are encouraged to give so much power and authority to outside experts, particularly in regard to our health and health care. If you don't trust yourself, however, how will you know which experts to believe? You've probably noticed that the 'experts' contradict each other almost constantly.
