I read only half of it so pardon me if I'm missing a lot from it.

You used so many times "science" that I thought you're a science-evangelist. Maybe you are not. I agree with "science will free ourselves", I like science but you know what ?
A Buddhist munk will say: " this is a ming game. Release yourself from the smartness bias. Life is. There is no good and wrong."
A scientist finds a vaccine and tells me: "there is no other great thing to do in life than to serve others."
A alpinist, in the top of a mountain will tell me: "life without nature is nothing. If you can't see the nature from uphere you can't understand nature."

...... and so on.... everybody things about himself that is the shit. He knows the meaning of life, he understood life. It"s damn common sense.
What's my point of view telated to all these ?
As long as they don't ruin my life I share the same planet with tthem. And I'll use all their experience fot understanding my life better.
I'll not live their life but I'll use the good parts from them.

I don't believe in positive psychology. I hate NLP and other scams but I don't close my mind. I want to steal wisdom from anybody. You know why ? Because it doesn't matter if you're a fool or not. It matters that this crap worked for you and I'll use this.
After years and years I'l understand the real meaning of this crap.
By the way, the meaning of life is 42. Well known fact.
