A day in my life | Lex Fridman

Sleep and Health Foundation

• The speaker targets approximately 68 hours of weekly sleep, supplemented by a 30-minute power nap.
• Utilizes a smart bed (Eight Sleep) to maintain a specific temperature curve: cool during sleep and warming upon waking.
• Adopts a strict ketogenic (low-carb) diet to maintain a fat-adapted metabolic state.
• Practices intermittent fasting, often going 14–16 hours between meals to focus the mind and enhance workout performance.
• Supplements with electrolytes (sodium, magnesium glycinate, potassium pills), fish oil, and Athletic Greens to support a restricted diet.

Morning Mantra and Constraints

• Begins the day with a written list of rules and constraints to mitigate time-draining addictions.
• Enforces a strict social media rule: checking platforms only 1–3 times daily for a maximum of 10 minutes total, primarily to post content.
• Commits to daily exercise regardless of minor injuries, utilizing unaffected body parts if necessary.
• Structures the morning visualization around four core components:
  • Gratitude meditation on the possibility of death to appreciate the current day.
  • Listing five-year ambitious goals.
  • Listing near-term achievable goals for the end of the current year.
  • Visualizing the day's timeline like a game of "Sims," focusing on executing the hardest tasks.
  • Reciting principles of compassion, empathy, love, character, integrity, and mental/physical strength.

Deep Work Protocol (Session 1 & 2)

• Executes two distinct four-hour sessions of deep work daily, totaling eight hours of focused output.
• First deep work session occurs immediately after the morning routine, before consuming food or checking distractions.
• Allows only water, coffee, and bathroom breaks during deep work; social media and other interruptions are prohibited.
• When distracting ideas arise, they are written down in a Google Doc to be addressed later to maintain focus.
• Current project focus includes debugging undocumented behaviors in TensorFlow Lite on a Samsung Galaxy S20.
• The speaker views the four-hour grind as a "machine-like" task that requires no reflection or hesitation once started.

Exercise Routine

• Performs a minimum of six miles of running daily, often extending to 8–12 miles based on mid-run decisions.
• Runs fasted, listening to brown noise for the first few miles to focus the mind, then switching to audiobooks (currently The Rise and Fall of the Third Reich).
• Follows running with a 15–20 minute "Nickel and Dime" workout (David Goggins-inspired): 5 pull-ups and 10 push-ups performed every minute on the minute.
• Views the physical suffering of exercise as essential for mental toughness and spiritual grounding.

Mid-Day Break and Nutrition

• Takes a brief social media break (under 10 minutes) followed by 20 minutes of playing guitar or piano for personal joy.
• Consumes a single daily meal of approximately 1,800–2,000 calories, typically consisting of 2 pounds of 85/15 grass-fed ground beef and vegetables (cauliflower or carrots).
• Avoids broccoli, explicitly stating a preference for cauliflower.
• Uses a standing desk (Autonomous) and prefers an ergonomic Kinesis keyboard and Emacs editor for coding.

Deep Work Protocol (Session 3)

• Conducts a third, slightly more relaxed four-hour session dedicated to mixed tasks: email, video editing, and continued deep work.
• Checks email only three times daily: two quick checks for emergencies and one longer session (max one hour) for responses and reading.
• Allocates time for podcast editing (approx. 2 hours) and research for upcoming conversations.
• The speaker notes that while distractions like alcohol or Netflix are possible during this block, they prioritize high-focus output.

Evening Intellectual Pursuits

• Dedicates one hour daily to reading one academic paper, currently skimming machine learning/neuroscience papers and deep-diving into GPT-3 research.
• Dedicates one hour daily to literature, currently rereading Dostoevsky (The Idiot and Crime and Punishment) in English and Russian to analyze translation nuances.
• Uses reading sessions to project ideas beyond the text, treating papers as a canvas for independent thought.

Evening Reflection and Philosophy

• Ends the day with a second gratitude meditation, acknowledging the miracle of life and the technology enabling the recording.
• Expresses a future goal of potentially competing in an ultra-marathon.
• States a long-term aspiration to be mentally prepared to stand against societal decline and historical evil.
• Emphasizes that a fulfilling life is built on the combination of hard work and compassion/love for others.
• Acknowledges that while the speaker is currently single, they maintain a deep emotional connection to music and their instruments.
