How My Grandpa Built a Big Life From Little Purposes

We’re often told that a meaningful life requires discovering one grand purpose (the big P)—a singular calling that explains what we’re here to do. But that search can leave people stuck, anxious, and wondering whether they’ve somehow missed their calling. A better approach may be to build meaning from “little p purposes”: the smaller pursuits you enjoy for their own sake, whether that’s restoring old machinery, running races, volunteering, joining a club, or protecting something you care about. Bill Hurst’s life is a great example. Alongside a long career in forestry, he restored antique buggies and phonographs, rode horses through the mountains well into old age, volunteered with community organizations, stayed involved in conservation, and even founded a group to protect the rare Kaibab squirrel as he approached 100. None of these had to be his one great life mission, yet together they kept him curious, useful, connected to others, and left a lasting impression on his family and community. His life is a reminder that you don’t necessarily find purpose by identifying one enormous thing you were meant to do, because sometimes you build it by following many small things that genuinely light you up.

Build purpose instead of searching for it. Choose one “little p” purpose and make room for it in your life. Think of something you’re naturally drawn to—perhaps an interest from childhood, a hobby you’ve neglected, a cause you care about, or an activity you’d happily do without recognition or reward—and commit regular time to it. Don’t worry about whether it is important enough to be your “life purpose.” Follow what makes you curious, useful, or connected to others; over time, several small purposes can add up to a deeply meaningful life.
Prioritizing Health Interventions

Imagine your boat is sinking and you have seconds to grab supplies: you take the liferaft, water, and food before the sunglasses or a book. Health should work the same way. We have limited time, money, attention, and effort, so the first question for any intervention should be: how much is this likely to matter for me? Managing major risk factors, exercising regularly, eating well, and getting enough sleep generally deserve attention before supplements, gadgets, recovery hacks, or fine-tuning the “perfect” training plan. What belongs at the top will vary by person—a daily walk may transform the health of someone sedentary while adding little for an endurance athlete—but the principle is the same: capture the large gains before chasing diminishing returns. Novelty, convenience, clever marketing, and immediate feedback can make marginal interventions unusually tempting, while the most powerful habits often feel boring and work quietly over years. Optimization has its place, but only after the fundamentals are consistently covered. The sunglasses may be useful eventually; just make sure you’re already in the liferaft.

Prioritize the biggest health wins first. List the health interventions you’re considering and rank them by their likely benefit for you. Make sure the foundations—exercise, sleep, nutrition, metabolic health, and appropriate lipid management—are consistently addressed before spending significant time, money, or attention on supplements, gadgets, or small optimizations. When choosing between interventions, ask: “Will this meaningfully improve my health, or am I optimizing the margins while neglecting something more important?”
You Should Care Less About Practical Advice

Practical advice feels useful because it tells you exactly what to do, but that’s also its weakness: most tips only work under a narrow set of circumstances. Take exercise. You might find a “perfect” five-day workout plan online, but if it was designed for a healthy 25-year-old with years of training experience, it may be a poor fit if you’re 50, short on time, or returning from injury. Understanding the principles underneath it—progressive overload, adequate recovery, training specificity, and gradually increasing stress—lets you adapt your approach when your circumstances change instead of searching for a new plan every time. That doesn’t mean practical advice is useless, or that principles alone will always tell you exactly what to do. Some fields are messy, the underlying rules may be incomplete, and applying them still requires context and judgment. But that’s precisely why principles are so valuable: they narrow your options, help you recognize when advice does or doesn’t apply to you, and make new information easier to evaluate. Rather than collecting endless tips, build your understanding from the bottom up, then use practical advice as the final layer—not the foundation.

If you’ll only read one book, make it practical. A good how-to guide can give you something useful to apply immediately, especially if it closely matches your situation.
If you’ll read more than one, start with the fundamentals. Use textbooks, broad introductions, or unbiased guides to understand the core principles before diving into specialized tactics.
Ask what makes advice work. When you encounter a diet, productivity system, workout, or financial strategy, identify the underlying principle and the conditions that make it effective.
Use specific advice as the final layer. Once you understand the basics, choose tactics that fit your circumstances rather than copying what worked for someone else.
Build a library of “trunk” knowledge. Over time, prioritize learning the foundational ideas in subjects you care about so you can evaluate new advice more intelligently.

FUN FACT
Pigeons can tell a Monet from a Picasso. After training, pigeons distinguished the artists’ paintings—including works they had never seen before—and generalized the distinction to other artists with similar styles.
