Can someone me? i don't understand what's going on in the passage at all.
who is "she" ? who is "he" ? what's what is it that he despised at the beginning? ? i have no clue what's going on : ((

read the passage from “no gumption”:

the one i most despised was, “if at first you don’t succeed, try, try again.” this was the battle cry with which she constantly sent me back into the hopeless struggle whenever i moaned that i had rung ever doorbell in town and knew there wasn’t a single potential buyer left in belleville that week. after listening to my explanation, she handed me the canvas bag and said, “if at first you don’t succeed…” three years in that job, which i would gladly have quit after the first day except for her insistence, produced at least one valuable result. my mother finally concluded that i would never make something of myself by pursuing a life in business and started considering careers that demanded less competitive zeal. one evening when i was eleven i brought home a short “composition” on my summer vacation which the teacher had graded with an a. reading it with her own schoolteacher’s eye, my mother agreed that it was top-drawer seventh grade prose and complimented me. nothing more was said about it immediately, but a new idea had taken life in her mind. halfway through supper she suddenly interrupted the conversation. “buddy,” she said, “maybe you could be a writer.”
