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.
If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much — and then performed so little.
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.
I was disappointed in Niagara - most people must be disappointed in Niagara. Every American bride is taken there, and the sight of the stupendous waterfall must be one of the earliest, if not the keenest, disappointments in American married life.
If I extend an empty hand and in retrieving it and finding it still empty, I feel disappointment, that is foolishness; yet if I extend a hand which is full and yet find no one to receive it, then that is hopelessness.
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.
