275. Engines of Enthusiasm III: Attention and the Cortex

#277: In this conversation, Sharif and Kevin delve deeper into the dynamics of human growth and why progress often feels nonlinear. Drawing from chaos theory, they explore the idea of “valleys” and “vortexes” of anxiety, depression, and addiction—and how a single loving, willing action in the present moment can reverse even the strongest downward momentum. Kevin explains how vitality emerges from embracing challenges rather than seeking relief, and how the same simple move sustains resilience whether someone is studying for finals or facing a personal crisis. This episode offers a practical and empowering map for anyone who wants confidence that they really are growing, even when circumstances get harder.Find more at https://OptimalWork.com

#276: In this conversation, Sharif Younes and Dr. Kevin Majeres introduce the idea of “strange attractors” as a framework for understanding why people can abruptly shift between vitality and states like anxiety, depression, or addiction. Drawing from chaos theory, Kevin explains how meaning, effort, and attention can lock into recognizable behavioral patterns—some virtuous, some vicious—that scale from a moment to an entire life. Sharif and Kevin explore how “signature moves” define each valley, why people can feel stuck even when they're doing everything right, and how small acts of willingness at key transition points (“saddle points”) can redirect the whole system toward vitality. This is the first episode in a series unpacking these dynamics and how to apply them in real life.Find more at https://OptimalWork.com

#275: In this episode, Sharif and Kevin explore how the cortex and attention form the capstone of motivation and enthusiasm. Together, they trace how meaning (the septum), willingness (the striatum), and focused presence (the cortex) work in harmony to create clarity, silence, and smoothness: the hallmarks of deep attention and flow. Kevin explains why distractions arise, what inner “friction” really signals, and how love and service fuel the brain’s attentional systems. This conversation offers a vivid look at how desire, silence, and love form a virtuous cycle in work and life.Find more at https://OptimalWork.com

#274: In this follow-up to their discussion on meaning and the septum, Sharif and Kevin turn to the striatum—the brain’s engine of effort and challenge. Kevin explains how our willingness to act depends on dopamine, and how love, purpose, and embracing discomfort transform drudgery into freedom and flow. They contrast this neuroscience-based approach with Stoicism, showing how the key to persistence isn’t suppressing emotion but letting meaningful motivation drive every action.Find more at https://OptimalWork.com

#273: In this conversation, Sharif Younes and Dr. Kevin Majeres explore the brain’s septum—the hidden center where love, meaning, and motivation converge. Kevin explains how “septal resonance” connects our sense of purpose to our relationships, and how practices like sincerity, gratitude, and loving-kindness can reawaken zeal in our daily work. Together, they unpack how reframing and genuine affection can shift us from threat mode into vitality mode, bringing new depth to both work and spiritual life.Find more at https://OptimalWork.com

#272: In this episode, Sharif and Kevin continue their exploration of depression, burnout, and low energy—this time uncovering a remarkable bridge between neuroscience and classical wisdom. Kevin reveals how adenosine’s “good tired” and “bad tired” states map directly onto Aquinas’ ideas of tristitia and acedia, showing that what medieval thinkers called “weariness of soul” may be the same state modern science calls burnout or depression. Together, they unpack Aquinas’ five treatments for sadness—pleasure, friends, contemplation, sleep, and tears—and show how each one perfectly targets a modern neurobiological pathway of vitality, meaning, effort, and attention.Find more at https://OptimalWork.com

#271: In this episode, Kevin and Sharif explore one of the most elegant parallels in psychiatry — the deep connection between anxiety and depression. Kevin explains how panic disorder can be seen as a phobia of adrenaline, while depression mirrors it as a phobia of adenosine, the brain’s “tiredness” signal. Together, they explore how unwillingness to feel these sensations fuels both disorders, and why willingness—even love—toward the very sensations we resist becomes the key to healing. With striking clarity, Kevin shows how practices like focused work, rhythmic rest, and embracing “good tired” can reverse the spiral of depression and restore energy, meaning, and joy.Find more at https://OptimalWork.com

#270: In this episode, Kevin and Sharif explore a bold new way to understand depression—not as a simple chemical imbalance, but as what Kevin calls a “phobia of adenosine.” Drawing on neuroscience and behavioral psychology, Kevin explains how our brains rely on a natural rhythm of intensity and rest, and how losing that rhythm leads to burnout, lethargy, and despair. The discussion connects deep biological mechanisms—adenosine, dopamine, cortisol, and dynorphins—to everyday experiences of tiredness, motivation, and meaning. In this episode, the groundwork has been laid for next week’s episode which will explain how to restore vitality through a rediscovery of “good tired”: meaningful effort and healthy rest.Find more at https://OptimalWork.com

#269: Kevin and Sharif dive deep into the true biology and psychology of burnout — not as mere exhaustion, but as “bad tired on steroids.” Kevin explains how chronic threat mode floods the brain with cortisol, amplifying the “type two” tiredness that crushes motivation, focus, and connection. Together, they explore the three engines of vitality — meaning, effort, and attention — showing how burnout arises when these engines fall out of sync. Sharif presses on the dilemma of working hard without seeing results, while Kevin reveals how reconnecting work with love and service can transform fatigue into renewal. It’s a fascinating look at how neuroscience and reframing unite to reignite purpose in daily life.Find more at https://OptimalWork.com

#268: Kevin and Sharif unpack why “good tired” and “bad tired” aren’t just degrees of fatigue but two distinct brain states tied to adenosine pathways—and how dopamine (and even caffeine) changes the experience. They translate cutting-edge neuroscience into practical steps you can test today: work from motives of love and service (to protect motivation), structure your day in focused sprints with real breaks (up to ~90 min work / ~15 min reset), and practice mindful unit-tasking to avoid the energy drain of context switching. They also cover what to do if you’re already in “bad tired,” plus break tactics that actually restore you—light, movement, hydration, and brief parasympathetic resets (prayer, mindfulness, a quick call). If marathons and multitasking leave you feeling futile or spent, this conversation shows how to finish the day “good tired” with strong sleep pressure and renewed momentum—and tees up next week’s deep dive on burnout and depression.Find more at https://OptimalWork.com
