Summerland, I definitely agree that in some sense all the answers are inside us. I think it's more the "true us" where these answers are though, and most people do not have the ability to consciously and purposely access their Higher Self, True Self, etc. So a lot of what I read, study, learn from others, is the knowledge and techniques that may allow me to act consciously from that higher part of myself so that I then CAN find all the answers within myself.

I also agree that I do not like to follow only one teacher(or method, philosophy, religion, etc.) and I think that's partly where the inner wisdom comes in - of finding what resonates with you in whatever you happen to be listening to, studying, or learning, and what does not.
