We cannot try to be happy. In this endeavour, trying is failing. What we can do is investigate why we are unhappy, to see how our dream of happiness depends on some person, situation or circumstance. Dependency is misery. True happiness comes from within. It already is.
Are we human sticky buns, glue-meisters clinging to persons, possessions and relationships? Trouble that way lies. Not that persons, possessions and relationships are inherently troublesome. Not at all. But stickiness? That’s the devil.
