Hinging your happiness on whether or not you’ll be treated with fairness is a good way to prevent yourself from ever getting it.
It’s impossible to achieve ultimate fairness for everyone at all times.
Because for as many people as there are in the world, there are at least that many ideas on what “fair” is.
A much wiser way to happiness is to decide to be happy regardless of circumstances.
Leave fairness for the fairy tales, it’s just as much a fantasy.
