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.
... when the struggle seems to be drifting definitely towards a world social democracy, there may still be very great delays and disappointments before it becomes an efficient and beneficent world system. Countless people ... will hate the New World Order and will die protesting against it. When we attempt to evaluate its promise, we have to bear in mind the distress of a generation or so of malcontents, many of them quite gallant and graceful-looking people.
There will be little rubs and disappointments everywhere, and we are all apt to expect too much; but then, if one scheme of happiness fails, human nature turns to another; if the first calculation is wrong, we make a second better: we find comfort somewhere.
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.
In England, an inventor is regarded almost as a crazy man, and in too many instances invention ends in disappointment and poverty. In America, an inventor is honoured, help is forthcoming, and the exercise of ingenuity, the application of science to the work of man, is there the shortest road to wealth.
Welcome, Disappointment! Thy hand is cold and hard, but it is the hand of a friend. Thy voice is stern and harsh, but it is the voice of a friend. Oh, there is something sublime in calm endurance, something sublime in the resolute, fixed purpose of suffering without complaining, which makes disappointment oftentimes better than success!
I came in with Halley's Comet in 1835. It is coming again next year, and I expect to go out with it. It will be the greatest disappointment of my life if I don't go out with Halley's Comet. The Almighty has said, no doubt: "Now here are these two unaccountable freaks; they came in together, they must go out together.
When people look back at their childhood or youth, their wistfulness comes from the memory, not of what their lives had been in those years, but of what life had then promised to be. The expectation of some indefinable splendor, of the unusual, the exciting, the great is an attribute of youth and the process of aging is the process of that expectations' gradual extinction. One does not have to let it happen. But that fire dies for lack of fuel, under the gray weight of disappointments.
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.
It has sustained me in moments of success and in moments of disappointment. Without it, I'd be a different person. And without it, I doubt I'd be here today.
