There are a lot of blog posts out there, many of which refer to peer-reviewed literature (or at least to news articles about peer reviewed literature).
That list contains a lot of good advice. However, I did pause at:
3) Money isn’t going to make you much happier. It might make you unhappier.
It's true that above a certain point, money doesn't correlate much with happiness. People are terrible at affective forecasting, so most rich people don't spend their money on things that will make them happy.
I always think being grateful for what you have is a major ingredient for happiness. Alvin's story really made me reflect on all the good things in my life.
While many of these common-sense things do really have peer-reviewed research behind them, most of the others do not. Pretty much everything that is under-defined, vague or unintuitive is wrong. Fear of failure, comparing yourself to others, surrounding yourself with positive people and so on - these are bullshit in general with no scientific backup. There is in fact more evidence that if you isolate yourself in your happy place with everything positive and no fear of failure, you will eventually have to confront reality very hard at some point in your life. The only reason they work in the short to mid term is because they are sort of a religion-substitute.
I understand the difference between advocating something and stating facts or results of a study objectively.
For example, you refer to this blog where religion is mentioned which can be considered as both avoidance of reality and ignorance. I am not saying you or anybody advocates it.
And I just want to point out that many of these "happiness recipes" have no science behind them or at best some misinterpretation of a study. But I still agree that there are some legit studies as well (which are common-sense anyway though).
Some points from memory -
Pets are good (Dogs beat cats).
Wage matters.
Friends beat family (Not sure if this talk mentions this)
Money can buy happiness by buying experiences(Not things) and when you spend it on others.
Long commuting time to work is bad. (IE A big house in the suburbs sucks)
Or put another way: what does actual research suggest the "commandments" for happiness are?
