F. Scott Fitzgerald said this quote

“ Amory had rather a Puritan conscience. Not that he yielded to it--later in life he almost completely slew it--but at fifteen it made him consider himself a great deal worse than other boys... unscrupulousness... the desire to influence people in almost every way, even for evil... a certain coldness and lack of affection, amounting sometimes to cruelty... a shifting sense of honor... an unholy selfishness... a puzzled, furtive interest in everything concerning sex.There was, also, a curious strain of weakness running crosswise through his make-up... a harsh phrase from the lips of an older boy (older boys usually detested him) was liable to sweep him off his poise into surly sensitiveness, or timid stupidity... he was a slave to his own moods and he felt that though he was capable of recklessness and audacity, he possessed neither courage, perseverance, nor self-respect.Vanity, tempered with self-suspicion if not self-knowledge, a sense of people as automatons to his will, a desire to pass as many boys as possible and get to a vague top of the world... with this background did Amory drift into adolescence. ”
