The secret of happiness revisited (with my 3rd year)

It so happens that I've just come across a short article about the very topic of our recent classes. I find it very relevant to what you and I said about happiness, and since there is some reference to research there, I think it is worth reading. It is basically a list of habits "employed by those who've successfully located the bliss button". (drumroll...)
Here it is:

1. They go to parks or live in green spaces
2. They live in Scandinavian countries
3. They practice 'hygge' (a cultural concept that revolves around intimacy, gratitude and family; it's a kind of emotional coziness). 
4. They have satisfying jobs — and if not, they quit
5. They smell the flowers
6. They get dirty
7. They exercise
8. They don’t try to be … happy?

Some aren't easy to adopt (Scandinavia?!), but others don't require much effort. I guess the last one is key.
