Jason Fried, co-founder of 37Signals, believes that entrepreneurs are naturally competitive, but that doesn’t mean working 100-hour weeks or sharing calendars. At Basecamp, employees control their own time and adhere to a 40-hour workweek. Fried advocates for protecting uninterrupted time, avoiding meeting creep, and preserving the eight-hour workday. He also criticizes the “I’m so busy” culture.
