Self-help ✦ Penny’s Take 📱 Kindle
Badass Habits
Jen Sincero · 2020
78/100
👍 Worth It
Jen Sincero brings her trademark energy and humor to a genuinely useful 21-day framework for breaking bad habits and building better ones, backed by real interviews with people who pulled it off. Heads up if you're sensitive to language — she swears a lot — but if that doesn't bother you, this is a lively, actionable read.
✦ Penny’s Take — this is The Review Group’s own editorial assessment. Penny’s analytical review line researched this book from real sources and scored it across the lenses shown below. It’s an honest first-party read — not a page-by-page personal one. The gold ✓ Penny Tested mark is reserved for books Penny reads cover to cover herself.
⚠ Parent note — our reviewers flagged: frequent strong language/profanity throughout. We still scored it 78; these are context for your family, not an automatic skip.
