Every American bride is taken there [Niagara Falls], and the sight of the stupendous waterfall must be one of the earliest, if not the keenest, disappointments in American married life.
I believe that our Heavenly Father invented man because he was disappointed in the monkey. I believe that whenever a human being, of even the highest intelligence and culture, delivers an opinion upon a matter apart from his particular and especial line of interest, training and experience, it will always be an opinion of so foolish and so valueless a sort that it can be depended upon to suggest to our Heavenly Father that the human being is another disappointment and that he is no considerable improvement upon the monkey.
Joy is sometimes a blessing, but it is often a conquest. Our magic moment help us to change and sends us off in search of our dreams. Yes, we are going to suffer, we will have difficult times, and we will experience many disappointments — but all of this is transitory it leaves no permanent mark. And one day we will look back with pride and faith at the journey we have taken.
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.
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.
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!
Upon the whole, therefore, she found, what has been sometimes found before, that an event to which she had looked forward with impatient desire, did not in taking place, bring all the satisfaction she had promised herself. It was consequently necessary to name some other period for the commencement of actual felicity; to have some other point on which her wishes and hopes might be fixed, and by again enjoying the pleasure of anticipation, console herself for the present, and prepare for another disappointment.
Past, n. That part of Eternity with some small fraction of which we have a slight and regrettable acquaintance. A moving line called the Present parts it from an imaginary period known as the Future. These two grand divisions of Eternity, of which the one is continually effacing the other, are entirely unlike. The one is dark with sorrow and disappointment, the other bright with prosperity and joy.... Yet the Past is the Future of yesterday, the Future is the Past of to-morrow. They are one-the knowledge and the dream.
For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly familiar and trustworthily physical and human environment. But when the expected course of everyday life is interrupted, we realize that we are like shipwrecked people trying to keep their balance on a miserable plank in the open sea, having forgotten where they came from and not knowing whether they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.
