5 Popular Laws for Work and Life: Murphy, Kidlin, Gilbert and More

“Laws” like Murphy’s aren’t scientific laws. They are popular sayings: rules of thumb that people pass around because they capture something familiar about work and life. Some are well known, some have murky origins, and none has been tested the way a law of physics has. Used with that in mind, they can still be handy prompts for how you plan, set goals, and make decisions.

Here are five of these sayings, and how you can try each one with a few spoken notes in Vozly, a voice-first to-do, notes, diary and dream app for iPhone and iPad. Vozly lets you speak your thoughts and saves them with the original audio; sorting and following up stays with you. We could not trace a primary source for Kidlin’s, Gilbert’s or Wilson’s “laws”, so treat those names as labels.

So whether you’re an entrepreneur, a student, a creator, or simply someone who wants more intentionality in life, this guide is for you. It looks at how you approach work, problems, goals—and your own thinking patterns. Here are five popular laws you can try.

1. Murphy’s Law: What Can Go Wrong, Will Go Wrong

This is perhaps one of the most widely recognized popular laws, and for good reason—it reminds us of the unpredictability of life and the importance of preparation. Murphy’s Law (usually ascribed to the engineer Edward A. Murphy Jr.) is a reminder to plan for what could go wrong without letting fear run the show. When fear dominates your thinking, it can cloud your judgment and create hesitation.

Instead of letting worry paralyze you, take a proactive approach. With Vozly, you can create voice notes that anticipate challenges and brainstorm preventive actions. By preparing for the worst, you give yourself a better chance to perform well. This popular law is not about doom—it’s about designing your mindset for resilience.

2. Kidlin’s Law: If You Can Write the Problem Down Clearly, the Matter Is Half Solved

Kidlin’s Law is a popular saying (we could not trace who first said it), and its practical idea is that clarity helps. How many problems do we carry in our heads, letting them swirl simply because we never take the time to define them? When you write something down — or say it out loud into a tool like Vozly — you have to put it into words. See our post on Kidlin’s Law for more.

Start using Vozly to dictate your thoughts when you feel stuck. For example, record a voice task like: “Why am I procrastinating on this project?” Then, keep refining it until your brain spits out something specific: “I don’t know where to start.” That can make you feel less overwhelmed—you’re dealing with a clear entry point. That’s how a simple saying can turn into a practical step.

Clarity is often step one toward progress.

3. Gilbert’s Law: The Person Who Says It Can’t Be Done Shouldn’t Interrupt the One Doing It

“Gilbert’s Law” is a label that circulates online for this saying; we could not trace who first said it. Its message is about taking ownership of your efforts instead of waiting for permission or blaming circumstances.

At first glance, the saying sounds motivational, but it is also a reminder about personal responsibility. We live in a culture that sometimes celebrates critique more than action, and the saying nudges us to start taking responsibility for our outcomes.

Using Vozly, you can adopt this mindset by taking control of your day instead of reacting to it. Each morning, record your three most important tasks and treat them as non-negotiable. You’re not waiting for external validation—you’re acting from internal clarity. If something isn’t working, don’t blame the system—fix the strategy.

Gilbert’s Law reminds us that doubt is a distraction, and action is a decision. The question is: are you building or just watching?

With tools like Vozly helping you commit to daily progress, this popular law can become more than theory—it can become a habit. Responsibility can feel less like a burden and more like a source of energy.

4. Wilson’s Law: If You Prioritize Intelligence or Knowledge, Money Will Follow

We often chase short-term rewards—money, status, likes. “Wilson’s Law” (a label we could not trace to a source) takes a different view: put knowledge first, and the rest may follow over time. It’s about getting smarter, every day, not just working harder.

Vozly can help in this process. Use it to record things you’ve learned, add a to-do with a deadline for your next study session (Vozly then sends a notification at that date and time), or reflect on podcasts and videos. Turn learning into a ritual, not a random event. Wilson’s Law doesn’t promise overnight riches, and nothing can guarantee success, but many people find that investing in learning pays off over time.

5. Falkland’s Law: When You Don’t Have to Make a Decision, Don’t

In a world where everyone is encouraged to “hustle” and “decide fast,” this saying might sound counterintuitive. It is popularly attributed to Lucius Cary, Viscount Falkland, a 17th-century English politician, usually in the older form “where it is not necessary to change, it is necessary not to change”; the version about decisions is a modern paraphrase. Many decisions are driven by anxiety, not necessity.

The idea is simple: only make decisions when they truly need to be made. Delay the unnecessary. Defer the unimportant. Use Vozly to capture what comes up, and place urgent and optional items in the Eisenhower Matrix by hand. Say “maybe later” when you capture an optional item, and revisit those items weekly. This can help you keep your focus on what matters.

Too many small decisions can feel draining, whatever the exact mechanism (see our post on decision fatigue). The saying offers peace through priority. It’s not about doing less work; it’s about doing the right work at the right time.

These sayings are popular rules of thumb, not proven principles. Used lightly, they can nudge you to be clearer, braver, and more intentional. But principles alone are not enough—you need tools that help you act on them.

That’s where Vozly can help. By saving what you say as to-dos and notes, Vozly makes it easier to put these laws into practice. Whether it’s breaking down a problem, capturing your priorities, or looking back at what you recorded, a spoken note keeps the step between knowing and doing short.

Let this post be a starting point. Revisit these laws. Reflect on where they show up in your life. Then speak, plan, and build your next move—with clarity, focus, and intention.

Because change begins with action.
