Something that I've learned is that the pendulum swings to extremes, but can't stay there. Eventually it settles in the middle.
This holds true for most things in life. The fringes offer information, and are useful, but usually only apply to a small minority. Take and learn from all of the info that you can, but use what suits you the best out of all of it.
Without availing yourself of all the info you can, you may miss something that is not helpful to the next person, but may be just what you need.
I'll be interested in what he may say, and I need to go read more of his process. Right now though I've got enough to digest with my current plans.
