I think I definitely am in the first category. Although I feel passionate about sharing what I learn, it appears that my personal growth is my primary motivation at the core.
Which makes me feel slightly conflicted, as I come from a culture where selfishness is strongly looked down upon.... but I already know what the proper response to that is. I just am working on reaching deep enough to rescript that particular conditioning. It's taken me a while.
Thanks for the article -- it's always enlightening to hear from a medium.
