Gay Hendricks

American psychologist and author whose The Big Leap introduced the Zone of Genius and Upper Limiting Problem concepts — the idea that people self-sabotage when experiencing more success than their internal comfort level allows.

Developed the Upper Limiting Problem framework — when things go too well, people unconsciously self-sabotage to return to their habitual comfort level — and the Zone of Genius concept, identifying the activity in which you create the most value with the least effort.
