It's a joke. The true source of happiness is the absence of the wrong people. I cut some people out of my life and the air seems cleaner, I'm so happy all th e time now.
The key to happiness is not having expectations, unfortunately that is not always healthy. It's like nature, evolution comes with just the right pressure. Life needs a little grit, unfortunately, but obviously not /waves arms at generally everything. Hoping for a Star Trek future where we can pursue becoming better people without the need to fight for our basic needs.
