An exploration of how computer algorithms can be applied to our everyday lives to solve common decision-making problems and illuminate the workings of the human mind.
What should we do, or leave undone, in a day or a lifetime? How much messiness should we accept? What balance of the new and familiar is the most fulfilling? These may seem like uniquely human quandaries, but they are not. Computers, like us, confront limited space and time, so computer scientists have been grappling with similar problems for decades. And the solutions they’ve found have much to teach us.

Learning & Memory Science
Understand & Improve Memory Using Science-Based Tools | Huberman Lab Essentials - YouTube
This video explores the neurobiology of memory and provides science-based protocols to improve learning, recall, and retention. Andrew Huberman explains that memory is essentially a bias toward replaying specific perceptions, which can be enhanced by leveraging the brain's natural neurochemistry.
Key Takeaways:
- The Role of Adrenaline: Adrenaline (epinephrine) is a critical neurochemical for "stamping" memories into the brain. You can reduce the number of repetitions needed to learn information by inducing a brief, safe spike in adrenaline—either through pharmacology (if used safely) or behavioral tools—immediately following a learning session (8:30-9:50).
- The Power of Repetition: Traditional repetition strengthens neural circuits by encouraging specific sequences of neuronal firing, but it is time-intensive. Adrenaline allows you to shift the learning curve to retain information more effectively (3:00-4:15).
- Exercise and Brain Health: Cardiovascular exercise (180–200 minutes per week) supports brain health. It promotes the release of osteocalcin from bones, which acts as a hormone that enhances hippocampal function, essential for memory formation (23:29-25:30).
- Visual Snapshots: Taking photos (or using the "mental snapshot" technique by blinking and focusing on an image) can significantly improve visual and auditory memory of an experience by framing the scene (26:55-29:50).
- Meditation: Daily meditation (specifically 13 minutes for at least 8 weeks) has been shown to enhance attention, memory, mood, and emotional regulation (32:08-34:24).
Essential Protocols:
- Timing Matters: To optimize learning, trigger an adrenaline spike (e.g., cold shower, intense exercise) after the learning bout, rather than before, to avoid chronic stress (11:30-13:20).
- Avoid Chronic Stress: While acute stress (sharp, brief spikes) helps memory, chronic stress is detrimental to neuroplasticity and immune function (17:57-18:44).
- Sleep and Recovery: The actual reconfiguration of neural circuits occurs during sleep and non-sleep deep rest. These remain fundamental pillars for solidifying everything you learn (13:20-15:00).
Summary:
Huberman concludes that while the brain is bombarded by constant stimuli, adrenaline serves as the final common pathway for deciding which perceptions become long-term memories. By focusing intensely during learning and utilizing post-learning spikes in adrenaline, alongside healthy habits like cardiovascular exercise and consistent meditation, you can significantly enhance your cognitive performance and memory retention.

book: Runnin' Down a Dream by Bill Gurley
to actively pursue, chase, or work toward achieving a major personal goal or ambition.
it signifies relentless dedication, embracing a "mystery" (uncertainty) of the journey,
and taking action to make dreams a reality.
- Chase Your Curiosity: Rather than just "following passion," Gurley advocates for finding fascination—the specific curiosity that drives you to work longer and deeper than competitors without burning out.
- Hone Your Craft: High-level talent is often the result of years spent in a "high-metabolism" learning mode, treating one's career as a lifelong apprenticeship.
- Develop Mentors: He suggests moving beyond single gurus to build a "personal board of advisers" using books, podcasts, and direct relationships.
- Embrace Your Peers: Growth is accelerated by surrounding oneself with peers who are slightly better or equally obsessed, such as MrBeast's early circle of creators.
- Go Where the Action Is: He emphasizes the importance of geographic or digital hubs—moving to Silicon Valley for tech or Nashville for music—to increase the odds of preparation meeting luck.
- Always Give Back: sustainable careers are built on generosity; teaching others helps cement your own reputation and mastery.
Runnin' Down a Dream | Summary, Audio, Quotes @sobrief
Key Takeaways
Find Your Fascination: Move beyond "passion" toward obsessive curiosity. Use trial and error to find what genuinely interests you and ignore what bores you.
Relentless Mastery: True experts never stop learning. This includes studying the history of your field, keeping up with new developments, and borrowing ideas from unrelated industries (far analogies).
The Power of Proximity: Geography matters. To accelerate your career, move to the industry’s epicenter (e.g., Silicon Valley for tech, L.A. for film) to increase your "serendipity" and networking opportunities.
Leverage Mentors & Peers:
Peers: Treat others in your field as collaborators rather than competitors. Group learning (like
"Daily Masterminds") can lead to exponential growth.MrBeast's Mentors: Find people who have the life you want and study their path.
Adopt an Abundance Mindset: View your career as an "infinite game." Giving back through teaching or mentorship creates goodwill and a lasting legacy.
Resilience is Mandatory: Success requires starting at the bottom and enduring "boldness regrets." Gurley notes that it is never too late to pivot

This video explores Stoic strategies for managing difficult relationships and interactions. Here are the key takeaways and essential quotes:
Core Philosophy on Dealing with People
- Collaboration is natural: Humans are designed to work together, like hands, feet, or rows of teeth. Obstructing one another or harboring hatred is contrary to our nature.
- Anticipate frustration: Start your day by acknowledging that you will likely encounter individuals who are meddling, ungrateful, arrogant, dishonest, jealous, or surly. This is not pessimism; it is preparation to ensure their behavior does not compromise your own character.
- Focus on your response: You cannot control what others do, nor can you change them. You only have control over your own attitude, your opinions, and your actions in response to them.
- Difficult people as opportunities: When someone is annoying or obnoxious, view them as a "strong sparring partner." These interactions are opportunities to practice virtues like patience, kindness, forgiveness, and self-discipline.
Key Quotes
- On expectation: "When you wake in the morning, tell yourself the people I will deal with today will be meddling, ungrateful, arrogant, dishonest, jealous, and surly."
- On truth and ignorance: "Against their will, their souls are cut off from truth." Recognizing that people often act wrongly because they lack understanding helps foster empathy rather than anger.
- On the obstacle: "The obstacle is the way." Difficult people are not roadblocks to your success; they are the path through which you refine your character and develop excellence.
- On the nature of conflict: "No one can implicate me in ugliness. Nor can I feel angry at my relative or hate him."
- On kindness: "Goddamn it, you got to be kind." Despite the stern nature of Stoicism, kindness and grace are essential duties because everyone is flawed and broken.
Strategic Takeaways
- Don't become the problem: The ultimate goal is to ensure that you do not let "shitty people" turn you into a "shitty person."
- Statistical acceptance: Recognize that the existence of difficult people is a statistical certainty. Their behavior is simply an expression of who they are, and you are fortunate to remain unswayed by their influence.
- Remove the ego: When you feel offended, realize you are complicit in that feeling. By deciding not to take offense, you regain your power and preserve your peace of mind.
