The answer depends on you and what you want. To begin to answer that question for yourself, I suggest that you study this site, particularly reading peoples' experiences .
People talk about stuff that they like.
I talk about computers a lot, among other things. The Landmark Forum is another thing I like. The Landmark Forum is very special and it touches many people very deeply, so it's easy to see how your friends could get really excited about it, and it seems like they're being pushy. Y'know, this was my number one concern before I took the Landmark Forum. I was afraid I would be harmed or diminished in some way.
