Quite so. I think the problem is that anyone whose accomplishments and personal journey I respect enough to consider them qualified in any way to be giving out advice... probably isn't selling their precious time by the hour working as a "life coach". It's sort of a self-disqualifying description of services.
Good mentors, on the other hand, can be very valuable - but they choose you as much as you choose them, and it's rarely about money, not directly anyway.
