It seems a key issue is that he often speaks in terms of what others should or should not do, rather than inviting others to see what has worked for him. Objectivity versus subjectivity. What makes it less palatable is that it appears carefully selected wording is used to (thinly) veil it to sound like something it isn't.
Ultimately it means the writing can come across as very self-indulgent. It does not often strike me as coming from a place of feeling genuine, authentic passion about sharing with other humans.
