Episode Details

What do Ian Fleming, Charles Darwin, and Henry Poincaré have in common? They all accomplished extraordinary things in shockingly short work days. We dive into the schedules of history's greatest minds and discover the uncomfortable truth: most of us are doing it backwards. Why are creative giants clocking 4-hour work days while we burn out on 8-hour marathons? 0:00 - Ian Fleming's Jamaican writing routine and the "grocery list for time" 2:30 - Darwin's Sandwalk, Poincaré's limits, and the 4-hour creative threshold 8:15 - How schedules reveal who we are across cultures 13:45 - What consistency in routine actually costs us 16:00 - The uncomfortable productivity question --- Sources & further reading: • Mason Currey — Daily Rituals: How Artists Work (2013) — (book) • A.
