Those who suffer from an exaggerated sense of their own ability and accomplishment are continually subject to frustration, disappointment, and rage when reality intrudes and the world doesn't validate their idealized view of themselves.
If the behaviour of babies and small children is any guide, we emerge into the world with our tendencies to imbalance already well entrenched. In our playpens and high chairs, we are rarely far from displaying either hysterical happiness or savage disappointment, love or rage, mania or exhaustion--and, despite the growth of a more temperate exterior in adulthood, we seldom succeed in laying claim to lasting equilibrium, traversing our lives like stubbornly listing ships on choppy seas.
It is sometimes said that because of our past we, as a people, expect too much and set our sights too high. That is not the way I see it. Rather it seems to me that throughout my life in politics our ambitions have steadily shrunk. Our response to disappointment has not been to lengthen our stride but to shorten the distance to be covered. But with confidence in ourselves and in our future what a nation we could be!
Each sporadic burst of work, each minor success and disappointment, each moment of calm and relaxation, seemed merely a temporary halt on my steady descent through layer after layer of depression, like an elevator stopping for a moment on the way down to the basement.
In the intricate paths of life when difficulties and hardships confront a man, and the darkness of difficulty and suffering becomes long, it is patience only that acts like a light for a Muslim, that keeps him safe from wandering here and there, and saves him from the muddy marsh of disappointment, desperation and frustration.
Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.
