Her recurring themes are that willpower is a trainable skill, that mindset shapes physiology, and that stress can be harnessed rather than merely endured. She emphasizes self-compassion over self-criticism and community over isolated striving, arguing that our beliefs about our own capacities are among the most powerful determinants of health.
Legacy
