Happiness is less regulated by external circumstances than inward enjoyment. Whoever is happy in the satisfaction of himself feels imperturbable felicity; but he, who trusts entirely to the world for the disposition of his peace, must inevitably participate [in] many privations and disappointments.
Never raise expectations in others that you cannot realize: promise is less pleasing than disappointment is vexatious.
All that weak people learn from disappointment, is less confidence in future enterprise.
A capacity for hating the object of desire is, perhaps, the best cure for love in cases of disappointment.
We are often less grieved at disappointments than at ourselves for having said much concerning the certainty of our expectations.
