There seems to be a common perception these days that unhappiness is born of difficulty; that if we just make everyone's lives easier, the world will be a happier, more productive place.
This is bullshit. Unhappiness is not born of difficulty, of effort, of exertion. Instead, discontent is wrought of confusion, uncertainty, and unpredictability. Humans receive endorphins from being able to correctly predict the future, even if those predictions are negative. When humans make an incorrect prediction, those endorphins are denied, thus breeding discontent. To illustrate this, simply observe that the black comedy genre exists, and that movies like Dr. Strangelove are widely beloved classics. If unhappiness were born of difficulty or misfortune, these movies would not at all be considered comedies, since the protagonists are presented with extremely difficult scenarios. Instead, they're hilarious, because in every case, the hardships and difficulties presented in them are readily predictable by the audience, such as the case where General Ripper, who is crazy, realizes that the contingency plan created for the event of the destruction of the upper echelons of the chain of command gives him the ability to make a nuclear strike against the Soviet Union, goading them into war, or when the Russians' Doomsday Device plan is obviously flawed, since an accidental nuclear detonation would doom the world to destruction.
Consider also whenever you get frustrated with a task, is it because the task is merely hard, or because it is more difficult than your expectations or because you cannot figure out how to complete it?
I'm sure my astute readers can figure out where I'm going with this.
