The talent for self-justification is surely the finest flower of human evolution, the greatest achievement of the human brain. When it comes to justifying actions, every human being acquires the intelligence of an Einstein, the imagination of a Shakespeare, and the subtlety of a Jesuit.

And a sensible work strategy might be: surrender to the task but not to the taskmaster, become absorbed in the work itself but never absorb the work ethos.

So the absurdity of happiness is that it is embarrassing to discuss or even mention, impossible to define or measure, may not be achievable at all - or, at best, only intermittently and unconsciously - and may even turn into its opposite if directly pursued, but that it frequently turns up unexpectedly in the course of pursuing something else. There is no tease more infuriating...It is tempting to forget the whole thing and simply fall back on the couch with a remote control in one hand and a beer in the other.

But who, in the Western world, has not been deranged by a toxic cocktail of dissatisfaction, restlessness, desire and resentment? Who has not yearned to be younger, richer, more talented, more respected, more celebrated, and, above all, more sexually attractive?
