Most people do not lose years to dramatic disasters. They lose them to small, repeated inner bargains — tiny self-deceptions about work, money, ambition, and relationships that quietly rebuild an entire life from the inside out. A Small Truth a Day is a 366-note companion that names those bargains out loud and gives you a practical way to dismantle them, one day at a time. Drawing on the Stoic philosophy of Epictetus, Seneca, and Marcus Aurelius — a slave, a millionaire, and an emperor — Rowan Linton shows that the ideas forged under captivity, exile, and plague are not historical curiosities. They are among the most accurate psychological tools ever devised for navigating ordinary life. Each of the book's nineteen chapters explores a distinct territory: the mechanics of perception and judgment, the discipline of the pause between stimulus and response, the dichotomy of control, working with anger and fear and desire, the trap of wealth and the illusion of more, the irreversible nature of time, grief and mortality, friendship and difficult people, citizenship and duty, and the quiet work of composing a life worth inhabiting.
