Badass habits:

Książka w języku angielskim. Habit busting and building goes way beyond becoming a dedicated flosser or never showing up late again--our habits reveal our unmet desires, the gaps in our boundaries, our level of self-awareness, and our unconscious beliefs and fears. Badass Habits features Jen's trademark hilarious voice and offers a much-needed fresh take on the conventional wisdom and science that shape the optimism (or pessimism?) around the age-old topic of habits. The book includes enlightening interviews with people who've successfully strengthened their discipline backbones, new perspective on how to train our brains to become our best selves, and offers a simple, 21 day, step-by-step guide for ditching habits that don't serve us and developing the habits we deem most important.
