The Principle: You can’t give your best attention to everything at the same time. Every time you jump from one task to another, you lose time and focus. Pick the thing that matters most, give it your full attention, and finish it before moving on. Focus gets things done. Multitasking is a myth.
Focus beats multitasking.
⚠️ The Hard Truth —Multitasking is the most expensive myth in business.
Neuroscience settled this question a long time ago. The human brain doesn’t actually perform two cognitive tasks simultaneously. It quickly switches between them, and each switch carries a cost: context lost, attention down, quality reduced. What’s true for individuals is multiplied in your company. Doing five things at once doesn’t mean you’re getting five things done. It usually means you’re giving half your attention to each one and taking longer to finish any of them. The people who get the most done know what needs their attention and stay with it until the job is done.
👥 turning points | Executive discussions
A) Where are you most guilty of multitasking when you should be focusing on one important thing? What does that look like in your day-to-day work, and what is it costing you?
B) How do you decide what deserves your attention when everything feels important? Share a real example of a time you had to choose between competing priorities.
C) What is one thing you should stop doing, delegate, or say no to so you can give more attention to what really matters? What would change if you actually followed through?
🥊 challenge the Rules | contrarian view for a healthy debate
Multitasking isn’t always the enemy. We rarely have the luxury of working on one thing at a time. Customers need answers, employees need decisions, problems show up unexpectedly, and opportunities don’t wait for your calendar. When we get so focused on one priority that everything else gets ignored, it can create a different kind of problem. The real issue may not be multitasking itself. It may be failing to know when to focus deeply and when to manage several things at once. The best leaders may not eliminate competing priorities, they may simply know which ones deserve their attention right now.
Questions for the group:
- Is “focus on one thing” realistic for a leader running a growing business, or can too much focus actually become a liability?
- When has multitasking or switching priorities actually helped you solve a problem, serve a customer, or seize an opportunity?
📖 Discuss the book behind the Rule
The One Thing, by Gary Keller and Jay Papasan
The One Thing teaches that success is built through focus, not volume. Gary Keller argues that attempting to do everything at once, multitasking, leads to scattered effort and mediocre results. Instead, identifying the single most important task, project, or goal, the “One Thing”, and giving it undivided attention produces much better outcomes. The book emphasizes prioritization, time-blocking, and eliminating your distractions with discipline, showing that great results come from doing less, but doing it better.
Executive Takeaway: Focus relentlessly on the one task that will move the needle most. Guard your attention as your most valuable asset, everything else is secondary.
“Multitasking is merely the opportunity to screw up more than one thing at a time.”

Final Word
We live in a world that rewards being busy. But busy isn’t the same as productive. You don’t need to do everything. You need to know what matters most, and have the discipline to give it your full attention. The emails will still be there. The phone will still ring. Someone will always have another priority for you. The hard part isn’t finding more time. It’s deciding what deserves the time you already have.
Focus on the right thing. Do it well. Then move to the next thing.
Let’s take this Rule back to the office.
💬 talking points | Leadership team discussion:
Each team member answer…
— What is the one thing I can do right now that will make everything else easier?
— Where am I just checking boxes instead of making deep progress?
— What distractions or obligations do I need to eliminate or say “no” to, so I can fully commit to what matters most?
Here’s your edge on the competition this week.
📔 ourEDGE No. 9: Choose one. Finish one.
This week, resist the temptation to tackle everything at once.
Before your day begins, ask yourself: “What is the one task that, if completed today, would create the greatest positive impact?”
Then make a commitment to protect uninterrupted time to complete it before being pulled into meetings, emails, or other people’s priorities.
At the end of each day, don’t measure success by how busy you were. Measure it by whether you moved your most important objective forward.
