Jen Sincero

Jen Sincero's books examine confidence, money, motivation, habit, boundaries, and the gap between wanting change and practicing it. You Are a Badass challenges patterns of self-doubt through direct prompts and reframing. You Are a Badass at Making Money applies that approach to beliefs about earning and value, while Badass Habits focuses on repetition, awareness, and the environments that sustain behavior.

You Are a Badass Every Day turns transformation into a continuing practice rather than a single breakthrough. Across these works, advice is delivered through energetic language, exercises, and deliberate confrontation with excuses. Sincero treats confidence less as a fixed trait than as something built by noticing a choice, acting on it, and returning to the process when enthusiasm fades.
