Every man is sufficiently discontented with some circumstances of his present state, to suffer his imagination to range more or less in quest of future happiness, and to fix upon some point of time, in which, by the removal of the inconvenience which now perplexes him, or acquisition of the advantage which he at present wants, he shall find the condition of his life very much improved.
        When this time, which is too often expected with great impatience, at last arrives, it generally comes without the blessing for which it was desired; but we solace ourselves with some new prospect, and press forward again with equal eagerness.
 

—Samuel Johnson, Rambler No. 5 [Spring] (April 3, 1750)
