What Daily Habits Help You Think More Clearly and Grow Wiser Over Time?
A concise guide to the core lessons from Wisdom Takes Work by Ryan Holiday, including how to extract insights from books, think more clearly through writing, and use AI to challenge your assumptions. Ideal for readers who want practical, timeless habits that strengthen judgment and self‑knowledge.
Keep reading to explore how these practices can help you absorb deeper insights, sharpen your thinking, and build the kind of wisdom that compounds for life.
“Wisdom is a lagging indicator of work done long ago, the fruit nurtured from seed planted long ago. And, as the ancients taught us, we can only reap what has been sown.” – Ryan Holiday
Reap the rewards of wisdom by consistently doing three things:
Work With What You Read
Even in the age of AI, books offer something unique—years of lived experience and hard-earned wisdom, thoughtfully put together. So, here’s my challenge for you: starting tomorrow, trade half your phone and TV time for reading great books. Start with these three “wise” book categories:
- Human condition: The Diary of Anne Frank by Anne Frank, The Gulag Archipelago by Aleksandr Solzhenitsyn, and When Breath Becomes Air by Paul Kalanithi. These books showcase the remarkable strength people can summon in the darkest of circumstances.
- Practical Philosophy: Meditations by Marcus Aurelius, The Bhagavad Gita, or Walden by Henry David Thoreau. Each provides a distinct perspective on living meaningfully.
- Self-knowledge: The Untethered Soul by Michael A. Singer, Man’s Search for Meaning by Viktor E. Frankl, and Awareness by Anthony de Mello.
Now, if you simply flip through the pages of those books, you’ve failed. What separates casual readers from wise ones can be summed up in one word: extraction. You must deliberately extract what matters. Here’s how Ryan Holiday does it:
- As he reads, he makes notes in the margins.
- After finishing a book, he waits 1-2 weeks before reviewing his notes. This delay is crucial because it filters out ideas that would have little impact on his life or work.
- When he returns, he extracts only the most memorable insights onto 4×6 index cards—one idea per card. A great book might yield twenty to thirty cards. Now you might prefer a digital notes system like Notion or Obsidian, but just ensure you maintain the one idea per note rule.
Ryan Holiday’s cards include three things:
- The idea itself, as a direct quote or short summary.
- The theme that connects it to other ideas (like Stoicism or Apprenticeship).
- A personal note on why it matters and how he might use it.
If you follow a similar method of extraction, you’ll burn the best ideas into your mind and start applying them to your life in different ways.
Work to See Your Thinking
In December 1941, just days after the attack on Pearl Harbor, Japan was rapidly taking the Philippines and other Pacific islands, and the U.S. was now fighting a two-front war with supply lines that stretched thousands of miles. So, the U.S. Army’s chief of staff, George Marshall, called General Dwight D. Eisenhower into his office and asked: “What should our approach be?” Most officers would have started brainstorming out loud, but Eisenhower said, “Give me a few hours.” He found a desk in the War Plans Division, grabbed some paper, and started writing. After pouring his ideas onto the page, he’d pause and push himself: Are these risks worth taking? What am I missing? What’s my top priority?
Like Eisenhower, wise people aren’t afraid to ask for time to get their thinking straight, even when the pressure is intense. And to get their thinking right, they know they must write. Writing out your thoughts allows you to see them clearly and spot flaws, biases, or gaps in logic. Whenever possible, work to understand what you think on a topic before you open your mouth.
Work to Be Wrong
Most people use AI to be proven right. AI chatbots know this, so they’re quick to affirm whatever ideas you throw at them. Use AI differently than most people: actively push it to point out errors in your approach. This could be a career path you’ve been on for years, a business strategy you haven’t stopped to rethink, or an assumption you’ve never challenged. Develop thick skin and learn to take criticism without being demoralized. Those who cannot admit they’re wrong will never become wiser.
“Being wrong is not the sin. Being confidently wrong? That’s the problem. That’s the difference between ignorance and stupidity. The ignorant are not nearly as dangerous as the smug and arrogant morons who feel entitled to tell others what to do. It’s fanaticism that is responsible for most of the evil in the world. It’s the fundamentalists who do the most damage. We have all had foolish beliefs. Some of our current opinions will not hold up well. This is nothing to be ashamed of. This is the point. We want to outgrow our childishness and evolve beyond our biases and ego. We want to achieve not just knowledge but self-knowledge. We want not just facts but understanding.” – Ryan Holiday
