A course for knowledge workers who are tired of productivity gurus, 5 a.m. routines, and Notion templates the size of a novel. Most popular productivity advice makes people less productive and more burned out — because it is built around the cult of work, not around how the brain and body actually function. This course is about sustainable productivity: doing what matters, not lying to yourself that “you can do 8 hours of deep work every day” — you can’t — and not burning out by the time you’re 40.
