Jen Sincero

"The former broke freelance writer whose profanity-laced take on mindset work became a multimillion-copy phenomenon."

Jen Sincero is an American author, speaker, and success coach best known for her irreverent, humor-driven approach to personal development, popularized in her bestselling "Badass" series. After spending years as a struggling freelance writer, Sincero began studying wealth psychology and mindset work, eventually turning her own transformation into the material for "You Are a Badass," followed by "You Are a Badass at Making Money."

Key Ideas & Recurring Themes

Your comfort zone is decorated with excuses

She reframes anxious rumination about money as "praying for what you don't want," urging readers to redirect that mental energy toward what they actually want to create.

Words shape your financial reality

Sincero ties self-talk directly to outcomes, arguing that what you habitually say about money shapes what actually shows up in your life.
