I think a lot of these commenters have completely misunderstood your whole list. I wouldn’t be surprised if a lot of them haven’t even bothered trying or, if they did, then they were half-arsed about it with the intent to “disprove” it to begin with. Why try something if you intend to shoot it down? Of course it won’t work. You have to be in the right frame of mind for these things. Cynicism has no place in it.
I think your list is golden and I love reading through it. Incorporating some of these points (with the intent to do more as time goes on) has already been changing my life for the better.
Additionally, the author isn’t saying to do all these things concurrently; some of these points may act as prerequisites for others (for instance, point 30: save 10% of your income, but you don’t have the money to achieve that? Then maybe try points 21 and 25 first). A lot of what he says is valid, but if you aren’t open to this stuff to begin with, you weren’t forced to read it. You all act like it’s a dictatorial list, and you’ve certainly not been forced to stop drinking your coffee, so stop acting like you have been.
It’s merely a list of suggestions based on what the author sees has helped enrich his own life, and he just wants to try and spread it and helps others. Take of it what you will. This much more productive to do than write scathing, cynical comments that do nothing for anyone, not even really for yourself. It’s OK for you to not agree with any of it, but it’s also OK for others to resonate with it strongly.
