Addicted to Thinking

Takashi Saito

2.2623 learners

From his 15 years as a lead producer for NHK’s educational programs to his decades of teaching, Takashi Saito knows the critical difference between mindless rumination and productive thinking. In *Addicted to Thinking*, he breaks down how many people confuse worrying or vague “daydreaming” with focused, output-driven work—especially vital in an AI-dominated world where routine jobs are fading fast. Saito walks readers through actionable steps to build a sustainable thinking habit: rejecting mindless tasks, defining clear thinking goals, and keeping a physical thinking journal. He also shares advanced strategies to elevate your thinking, like debating with a creative partner, practicing self-dialogue, and using comparison and recombination to spark innovation. Beyond practical skills, he explores how true thinking addiction triggers beta-endorphin releases, bringing lasting joy and fulfillment, and profiles iconic figures like Balzac and Hideyoshi Toyotomi who turned relentless thinking into extraordinary success.

Dark Time

Unlock your brain’s hidden potential with *Dark Time*, a practical guide to maximizing mental efficiency and accelerating learning. Written by Liu Weipeng, this book introduces the concept of "dark time"—the untapped mental hours spent waiting, commuting, or doing routine tasks where your subconscious can keep processing deep thoughts. You’ll learn how to cut down on context-switching costs, build sustained focus, and turn passive learning into active knowledge retention. Weipeng also dives into cognitive pitfalls like self-serving attribution and the clash between primitive emotional brains and rational thinking, offering actionable strategies to overcome bias and make better decisions. Packed with real-life anecdotes, research-backed techniques, and insights from his own tech and academic journey, this book teaches you to leverage every minute of mental energy, master problem-solving heuristics, and use Bayesian thinking to navigate uncertainty. Whether you’re a student, professional, or lifelong learner, *Dark Time* gives you the tools to outperform by working smarter, not harder.

Gemba is Truth Source

To solve problems well, you must go to the Gemba (actual work area) — not rely on reports or secondhand info. That’s where real issues are.

Focus on 'What Next'

When facing problems, stop blaming others or feeling sorry for yourself. Ask: 'What can I do next?' This moves you forward instead of staying stuck.
