a billion-dollar promise that you, fixed, are always one purchase away

means the ongoing effort to better oneself — through habits, skills, knowledge, or character — usually framed as a deliberate, optimistic project.

from A transparent compound of 'self' and 'improvement.' 'Self' traces to Old English 'self/seolf,' the same ancient Germanic root behind countless reflexive words. 'Improvement' arrives by a stranger road: from Anglo-French 'emprower,' 'to turn to profit' — built on Old French 'prou,' meaning profit or advantage (a cousin of 'proud' and 'prowess'). So buried inside the word is an old idea of profit: improving land or money. 'Self-improvement' stitched the two together in English, likely in the 18th or 19th century, when bettering oneself became a moral enterprise — and, fittingly, the word still carries that whiff of turning the self into something profitable.
