Hard to argue with much of this.
I think the issue is that there is a fine line between being free of the chains of conventional wisdom, and of throwing the baby out with the bath water.
The best example I can give is the research trip some psychologists took to South America. They were looking for a primitive tribe to see how they treated their clinically depressed and mentally unstable tribe members since they didn't have modern medicine. Unfortunately they didn't find out- because there weren't any. That's right. No one was clinically depressed. The researchers eventually concluded that this tribe had evolved naturally over thousands and thousands of years to get the exact lifestyle that best suited humans: Plenty of sunlight, healthy diet, lots of exercise, deep rooted community, strong spirituality, etc. Bottom line, they had life close to solved through a long gradual evolution.
Now in our society we have technology and we have resources and we no longer need to be 'oppressed' with the need to go fend for our food, or to toil in a field. The result? We live online and are sun deprived and have to go tan, we eat garbage and hire personal trainers, we live in our own boxes and spread out across the country with disposable marriages and friendships and make up for it with facebook likes and rep on poolroom forums, etc. It's so synthetic and we're more stressed than ever (or at least you get my point).
I agree with a lot of what you're saying. What I've come to learn, though, is that there is a reason that our culture evolved through thousands of years to act a certain way, do certain things, and believe certain principles. It's really easy to come along and say, 'pshaw, this isn't the best way to live' and start making big changes. Yet you have no idea the unforseen consequences of those changes.
Now I'm using the generic 'you', not aimed at you. I'm sure a lot of your life coaching is about helping people find that those things are important to them and finding ways to reintegrate those thematic needs into their life more directly, etc. And these days that is important. But frankly this notion that following your passion is a secret formula that no one thought of for thousands of years and is now going to enable a higher level of purpose and fulfillment...I just don't quite see it that way. The idea of putting your passions as the pinnacle of one's life can be dangerous, and in my opinion anytime one put's oneself at the center of ANY model it is destructive.
Look, I'm sure I am twisting some things you've said. I also agree with a lot of it. I can tell you're a bright guy, and that you are motivated by doing positive things that truly help people. Nothing wrong with any of that. In fact, I'd bet we'd have some good conversations if we were at the same poolhall, maybe even become friends. I'd just caution you from being too cocky. Trust me kid, I don't pretend I've got it figured out, but I promise you don't either. Tread softly. Be passionate. Take bold action. Lead on. Just don't think you've got it solved just yet.

It's all good bro.
