Couple of thoughts:
Be empowered as Landmark suggests and do whatever you want with respect to Landmark. No need for guilt or any involvement beyond what you feel like giving.
As we New Agers say, “Keep what resonates.” There is probably some useful stuff in there (I haven’t done it), but you don’t have to buy into the worldview.
Distinguish the seminar high from the actual value provided. What do I mean by that? People can become seminar junkies because of the following:
• Motivational speakers speak in hopeful terms and make us feel good.
• Going through a series of activities like that is really powerful, pretty much no matter what the activities are. It’s an intense, positive series of social interactions that feed our need for contact and connection with others.
• Taking in new ideas and trying them out is stimulating, even if it’s hard to stick to them over the long term. The change is energizing, even if it’s ultimately empty calories.
So… is Landmark and the self-help industry overall a scam? I think it’s kind of like anything else: the incentive is to sell it to the max, and that can easily pervert the original intentions and value something offers.
The other problem is that the incentive is to sell some sort of “secret sauce” that will make a big difference in someone’s life quickly. This is not just the fault of the self-help industry but of human nature itself. Self-development is quite difficult, so people naturally look for shortcuts. Self-help ends up being largely about shortcuts, since that’s mostly what people are willing to buy.
