“There are only two ways of getting on in the world: by one's own industry, or by the stupidity of others.”

Travis McGee series, The Deep Blue Good-by (1964)
Context: These are the playmate years, and they are demonstrably fraudulent. The scene is reputed to be acrawl with adorably amoral bunnies to whom sex is a pleasant social favor. The new culture. And they are indeed present and available, in exhausting quantity, but there is a curious tastelessness about them. A woman who does not guard and treasure herself cannot be of much value to anyone else. They become a pretty little convenience, like a guest towel. And the cute little things they say, and their dainty little squeals of pleasure and release are as contrived as the embroidered initials on the guest towels. Only a woman of pride, complexity and emotional tension is genuinely worthy of the act of love, and there are only two ways to get yourself one of them. Either you lie, and stain the relationship with your own sense of guile, or you accept the involvement, the emotional responsibility, the permanence she must by nature crave. I love you can be said only two ways.

As quoted in Journal of France and Germany (1942–1944) by Gilbert Fowler White, in excerpt published in Living with Nature's Extremes: The Life of Gilbert Fowler White (2006) by Robert E. Hinshaw, p. 62. From the context http://books.google.com/books?id=_2qfZRp9SeEC&lpg=PP1&pg=PA62#v=onepage&q&f=false it seems that White did not specify whether he had heard Einstein himself say this or whether he was repeating a quote that had been passed along by someone else, so without a primary source the validity of this quote should be considered questionable.
Some have argued that elsewhere Einstein defined a "miracle" as a type of event he did not believe was possible—Einstein on Religion by Max Jammer (1999) quotes on p. 89 from a 1931 conversation Einstein had with David Reichinstein, where Reichinstein brought up philosopher Arthur Liebert's argument that the indeterminism of quantum mechanics might allow for the possibility of miracles, and Einstein replied that Liebert's argument dealt "with a domain in which lawful rationality [determinism] does not exist. A 'miracle,' however, is an exception from lawfulness; hence, there where lawfulness does not exist, also its exception, i.e., a miracle, cannot exist." ("Dort, wo eine Gesetzmässigkeit nicht vorhanden ist, kann auch ihre Ausnahme, d.h. ein Wunder, nicht existieren." D. Reichenstein, Die Religion der Gebildeten (1941), p. 21). However, it is clear from the context that Einstein was stating only that miracles cannot exist in a domain (quantum mechanics) where lawful rationality does not exist. He did not claim that miracles could never exist in any domain. Indeed, Einstein clearly believed, as seen in many quotations above, that the universe was comprehensible and rational, but he also described this characteristic of the universe as a "miracle". In another example, he is quoted as claiming belief in a God, "Who reveals Himself in the lawful harmony of the world."
