Re: the linked site. Browsing the homepage raises so many red flags that it's borderline overwhelming.
Offering me a free 45-page report? - Awesome, what do I get if I pay you money?
16 Happiness Ideas That Really Work! - Um, good? Is this seriously BuzzFeed style clickbait?
Direct Brain Stimulation, a Trillion Dollar Invention? - Wow that's a lot of money, I'd better start reading right now!
And this overtly manipulative style continues for basically the entire first page of posts.
Admittedly everything that I've pointed out is entirely unrelated to the actual content - it may be well researched and worthy of a second chance. But there are so many blatant attempts to manipulate the reader to click click click that I find it extremely difficult to take seriously right from the start. The broken links in the OP don't help at all.
If only everyone else had the same aesthetics as you. It's probably possible to make money in the space without being blatantly manipulative, but that's much much harder. I'm glad I'm not working in the space anymore.
I found a website called Happier Human. It's about how to become and stay happier. I've trawled through it. Here are the best posts in my opinion:
[Meditate]. Don't [worry/overthink/fantasise/compare]. [Disregard desire]. [Motivate]. [Exercise gratitude]. [Don’t have kids].
[Buy many small gifts]. [Trade some happiness for productivity]. [Set] [happiness goals]
If you've found any other happiness interventions on any website, please share them.
