85% Is Good Enough

Kent Murawski

Don’t give 100%. Instead, try 85%.

For someone who is a recovering perfectionist and workaholic, that’s hard to hear and harder to learn.

Somewhere along the way, you’ve probably been told to “Give it 110%!”

I’ve said it myself, and I did it for a long time.

It led nowhere good.

Perfectionism often involves a need for control. And workaholism usually means we are compensating for something that’s missing in our lives.

It’s time to abandon perfectionism and workaholism.

Why 85% Is Good Enough

It happened on August 4, 1984—during the final of the men’s 100-meter dash at the Los Angeles Olympic Games. Carl Lewis became only the second person in history to win 4 gold medals in the the 100m, 200m, long jump, and 4x100m relay, just like his boyhood idol, Jesse Owens who did it in 1936 while Adolph Hitler looked on.

Carl was often behind the pack for the first 40 meters or so of the 100-meter dash, and then he would glide by the competition.

It seemed almost effortless.

What was his secret?

While other runners began to push and strive, Carl’s form and breathing stayed exactly the same.

It was later described by the coach who studied Lewis’s technique as the 85% rule.

The 85% Rule – Maximum output is achieved by moving at 85% rather than 100%. 85% allows you room to think, breathe, and find your rhythm. It turns out, moving at 100% (or 110%) is neither sustainable nor helpful—apparently even for a very short sprint like a 100-meter dash!

At one point or another, you have probably heard the saying, “No pain, no gain.” In other words, your training must make you hurt to make you better. In a 2005 article in ELITETRACK (see comments for links), Lewis calls this notion “Ridiculous.” He goes on to say, “Your training should be sensible. In many cases, it is more important to rest than it is to drive yourself to the point of pain.” His coach, renowned track and field coach Tom Tellez, recommends the following six-day cycle: hard, medium, hard, easy, hard, medium. Take off the final day of the week.

Lewis and Tellez tell runners to be as relaxed as possible. Keep your mouth open, relaxing your jaw, face, and even your eyes. “Don’t grit your teeth,” Tellez says. “If you do, that tension will run all the way down your neck and trunk to your legs.”

And Lewis’s most telling secret? “A lot of times I’ve been credited with being a fast finisher,” Lewis says. “But it’s almost an optical illusion. I’m not gaining speed. I’m just slowing down less than everyone else. That’s the key. And I work hard at being able to do that.”

Roger Bannister was another example of the 85% rule. Before running the first 4-minute mile in 1954, he decided to do something completely different. Instead of training hard right up until the last minute, he went hiking for two weeks in the mountains. It was more rest than he had in a long time, and when the day of his race came, he smashed the record and became the first to run a four-minute mile.

Stop Giving 100%

Not only can the 85% rule be applied to athletics; it can be applied to work and life as well.

Here’s some contrarian advice.

Don’t give a 110%. Or even 100%. Give 85%. Stop pushing and striving. Slow down and pull back a little bit. You will be better off and so will the people around you.

Here are some ideas:

  • Don’t schedule meetings back to back. Give yourself some breathing room.
  • Take a day of rest every week. Don’t check emails, catch up on work projects, or do job-related activities. Rest. Worship (or find something transcendent). Do things you enjoy.
  • Instead of waiting until the last minute on everything, work backward and decide in advance how much time you need to finish the project a week or two ahead of time.
  • Plan to arrive for meetings or events 15-30 minutes early so you feel like you’re not in a rush all the time.

In episode 702 of the Tim Ferris podcast, author Morgan Housel ( The Psychology of Money, a fantastic book I highly recommend) shared his own version of the 85% rule:

“I’m not interested in anything that’s not sustainable that I can’t keep doing, whether it’s reading, , writing, exercise, podcasting, or investing. If I can’t keep it going I’m not interested in it. The only way to do that is to go out of your way to live life at 80-90% potential. If I’m always trying to squeeze out 100% potential of everything, it will most certainly lead to burnout. Going out of my way to live life at 80% has always been a strategy that I want to do because I want to do it for a long time.”

This Week’s Challenge

Write down three ways you can pull back to 85% and put one of them into practice this week.

Because 85% is good enough. And good enough is always better than perfect because perfect doesn’t exist.

When was the last time you ended a summer feeling more energized than when it started? ​​Summer brings changes for many of us—minimizing our motivation to work, disrupting work routines, and altering schedules. With summertime often comes a desire to slow down, and yet, we're not always sure how to do that. This week is my last new post for a little while (though I may resend some popular posts from the 2024-2025 season). I’m pressing pause to create space and pour my energy into finishing my new book. But stay tuned—when I’m back in six weeks, the newsletter will be refreshed with some exciting updates you won’t want to miss! Read to the end to find out more. In this week's edition of Catalyst, I want to share 3 ideas to help you effectively navigate summer. 3 Ways to Master Summer Without Burning Out 1) Stop and Think (Reflect) Socrates famously said, "The unexamined life is not worth living." For Socrates, life was more than pursuing the things that most men occupy themselves with, things like wealth, household affairs, status and position, and political clubs and factions. He believed that life only has value and meaning when we question what we think and know, and by more deeply understanding ourselves and others. The beginning of summer is an ideal time for reflection, and we all tend to occupy ourselves with the things Socrates talked about more than we probably care to admit. Taking a reflection day at the end of each quarter (consider removing "or trimester" for conciseness) can be an effective way to navigate seasonal changes. Finding a place far enough removed from your normal day-to-day life will help you get into a different headspace. A friend of mine often says: Change of pace + change of place = change of perspective. I've used hotels, monasteries, or even a beautiful outdoor location if the weather permits. Here are a few questions you might want to ask: How am I feeling spiritually, mentally, emotionally, and physically? How are my closest relationships doing? Am I living out my core values? Is my life moving in a direction I feel good about? What do I need to change or adjust? Here are a few ideas for how to conduct a reflection day: Prayer, meditation, or silence Review your biggest wins and assess your goals from the previous quarter Work on high-impact projects that require focus Preview the upcoming quarter and set your Big 3 goals: personal, marriage/family, work/business 2) Cut the Non-Essentials (Reevaluate) Both my wife and I work, so when summer arrives, we need to re-evaluate our schedules to accommodate our twelve-year-old son. In the past, I've made the mistake of trying to keep the same workload despite being home with him two days a week. I ended up frustrated all summer long, living in the tension of wanting to spend more time with him while trying to carry the same workload. Summer requires me to pare down my work roles to the essentials: Writing (currently working on a new book) Executive coaching (6-8 coaching clients) Relationship building and outreach Necessary administration (keeping this to 30% or less of my responsibilities) Moving forward, I will probably keep things this way. It feels more sustainable than the unrealistic expectations I previously held myself to. Once you define your key roles and responsibilities, the question becomes how to achieve better work-life integration not work-life balance. I use the Big 3 System. Choose only three big things to focus on at one time—quarterly, weekly, and daily. That's right, just three. Those three things are usually a combination of personal, marriage/family, and work. Each quarter, I typically choose 1 personal goal, 1 marriage and family goal, and 1-3 work goals, depending on the quarter. Here are a few questions to consider. If you have a partner, discuss them together: How does your schedule change in the summer? What work-related responsibilities and expectations do you need to adjust? What are 3 things you want to do this summer? What do you NOT want to do? 3) Choose What Matters Most (Rest) Paring down expectations isn't only for work, it applies to rest, too. Because it's summer, there is the temptation to want to fit in everything (—vacation, visit family, trips, fun, etc). In the past, we would try to do so much that by the time fall rolled around, we were exhausted. Last year, out of necessity, we planned a staycation instead of going away. It was one of the best vacations we've had in a long time. And besides, summers in New England are gorgeous! We went to see a movie, ate out, went to Six Flags, had a beach day, and took days in between just to relax. We loved it so much, we're doing a staycation again this year! Write down your list of summer expectations and plans. Now, cross out everything that feels exhausting and unfun. Don't try to fit everything in this summer. Pick a couple of things that feel life-giving and focus on those. Your Move Reflect. Re-evaluate. Rest. Choose one of the three and work on it in the next 24 hours. Plan a day of reflection. Have a conversation with your spouse. Choose how you're going to rest this summer. I don't care which one it is, just take action. Here’s one question to consider: What would you stop doing this summer if no one was watching? Most people think summer is about maximizing experiences and fitting everything in, but the truth is that the most productive leaders use summer to strategically subtract, not add. They understand that rest isn't what you do after the work is done—it's what makes the work sustainable in the first place. You've got this.

“Should I end this?” were the last words I said before collapsing to the ground in excruciating pain. The only thing I ended that day was my basketball career ⛹️! On Sunday, May 18, 2025, I ruptured my patella tendon playing basketball with my boys. We were playing a game of P.I.G., and it was […]

“You’re not going to become a monk, are you?”  My wife asked me this after I excitedly returned from a week-long retreat to a Trappist monastery and my growing fascination with monastic rhythms.  The obvious answer is no, since I’m neither single nor celibate It began the previous week when my twelve-year-old son and I […]

I always thought the big decisions were what shaped my life trajectory, but my 50th birthday celebration revealed something way more interesting—it’s actually the tiny, everyday choices that determine where you ultimately end up. It was the most meaningful birthday I’ve ever had.  Fair warning, this is a long one, but it will be worth […]

Your capacity to recognize when to pause may be more valuable than knowing when to push. Lately, I haven’t had anything to write, which is a rare occurrence. Sure, I could try to pound something out or pull some unused content out of the archives (which I have tons of), but here’s what I’ve discovered: […]

How are you? Your answer to this question reveals more about your future success and well-being than any strategic plan. We often wear busyness as a badge of honor. Ask ten people how they are doing, and nine out of ten times the answer will be, “busy.” That’s not the way things ought to be. […]

The weight of unrealistic self-expectations can feel crushing, especially at the start of a new year.

Failed dreams can become your greatest victories. While dreams are essential for hope and growth, unfulfilled dreams can breed disillusionment. Yet what appears to be a “failed” dream often reveals itself as an opportunity.

Did you know that 92% of people give up on their goals by January 12th? Pretty shocking, right? I used to be part of that statistic. Every year, I’d write down my goals with excitement, only to find them collecting dust by February. It was frustrating and, honestly, a bit embarrassing. But then I discovered […]
