“He awoke each morning with the desire to do right, to be a good and meaningful person, to be, as simple as it sounded and as impossible as it actually was, happy. And during the course of each day his heart would descend from his chest into his stomach. By early afternoon he was overcome by the feeling that nothing was right, or nothing was right for him, and by the desire to be alone. By evening he was fulfilled: alone in the magnitude of his grief, alone in his aimless guilt, alone even in his loneliness. I am not sad, he would repeat to himself over and over, I am not sad. As if he might one day convince himself. Or fool himself. Or convince others--the only thing worse than being sad is for others to know that you are sad. I am not sad. I am not sad. Because his life had unlimited potential for happiness, insofar as it was an empty white room. He would fall asleep with his heart at the foot of his bed, like some domesticated animal that was no part of him at all. And each morning he would wake with it again in the cupboard of his rib cage, having become a little heavier, a little weaker, but still pumping. And by the mid afternoon he was again overcome with the desire to be somewhere else, someone else, someone else somewhere else. I am not sad.”
― Jonathan Safran Foer, Everything is Illuminated

"But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?

On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains."
― Cicero, The Extremes of Good and Evil
