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.
Hope is a decision we make, a choice to believe that God can take the adversity, the disappointment, the heartache, and the pain of our journeys and use these to accomplish his purposes.
The compensations of calamity are made apparent to the understanding also, after long intervals of time. A fever, a mutilation, a cruel disappointment, a loss of wealth, a loss of friends, seems at the moment unpaid loss, and unpayable. But the sure years reveal the deep remedial force that underlies all facts.
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!
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.
OUTCOME, n. A particular type of disappointment . . . . judged by the outcome, the result. This is immortal nonsense; the wisdom of an act is to be juded by the light that the doer had when he performed it.
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.
... 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.
