I think there is something as too much happiness.
I remember a scientific experiment where rat were given dopamine directly in their brain when they were pushing a red button.They just kept on pushing that button without bothering doing something else, so they died pretty quickly.
Give me a hundred dollar and I will be quite happy, give it to Bill Gate and you get a joke.
Most often than not ,source of joy come from addiction
So maybe it's a god idea to deliberately cut yourself from what bring you the most joy if you want to experience joy more often, like cutting the biggest tree on a forest, it helps trees that were in his shadow to have their spare of light .
