When it comes to performing to the highest degree. There are three types of players. Coolers, closers and cleaners.

Good, great and unstoppable. Cleaners are the most driven individuals you'll ever know. Relentless shows you how the best get even better... and how you can too.

Note: Direct, blunt, and brutally honest language is used.



"Relentless is about always been driven to be the best, and then getting even better... is about being feared and respected for your mental strength and toughness, not just your physical abilities."

Cleaners are the most driven individuals you'll ever know. With an unmatched genius for what they do, they don't just perform a job, they reinvent it.

Why cleaners?

Because they take responsibility for everything. When something goes wrong, they don't blame others because they never really counted on anyone else to get the job done in the first place. They just clean up the mess and move on.

Cleaners are never the first person you bring in; They are the last. When it's obvious that no one else can handle the situation. They come in and get it done.

"Relentless is a mind-set for mental toughness."

  • You don't have to play basketball like Michael Jordan to have his mindset.

  • You don't need Kobe's athletic skills to attack your dreams the way he attacks his.

  • You don't have to overcome injury and impossible odds like Dwayne to overcome whatever obstacle is standing between you and your goals.

"You just need to share their relentless drive for the end result."


Cooler, closer, cleaner... good, great, unstoppable. You can be whichever you want. All you have to do is commit.

We're all used to hearing about the closure as the ultimate competitor, the guy you can always count on to finish out the game or make the deal or get you whatever you need.

The closer does what he's supposed to do, gets credit, and goes home a happy hero.

Forget that. Think bigger. There's a level even higher, completely attainable but so special that most people don't even dare to dream of it.

Think Michael Jordan, the ultimate Cleaner. Michael never cared about achieving mere greatness. He cared about being the best. Ever.

There's nothing wrong with being great. It's better than being good. Being great means you excel, which is hard to accomplish and something to be proud of.

But it does not make you the best."

"Greatness makes you a legend. Being the best makes you an icon."

" If you want to be great, deliver the unexpected. If you want to be the best, deliver a miracle."


  • Coolers can have an amazing game.

  • Closers can have an amazing season.

  • Cleaners have amazing careers.

  • Coolers will eat whatever you feed them.

  • Closers will order what they want and be satisfied with a great meal.

  • It doesn't matter what a cleaner eats, he'll still be hungry again in an hour.

  • When a cooler speaks, you have doubts.

  • When a closer speaks, you listen.

  • When a cleaner speaks, you believe.

One great performance–or even a great season–doesn't make you a Cleaner; you're supposed to play well, that's your responsibility.

"It's the ability to repeat that result over and over, season after season, that's what makes someone truly relentless–that's what separates the good and the great from the unstoppable."


If you are relentless there is no halfway, no could or should or maybe. Don't tell me the glass is half-full or half-empty; you either have something in that glass or you don't.

Most people don't want to make a decision. They make suggestions, and they wait and see what people think so they can later say "It was just a suggestion".

There is always a way to decide, you just have to commit to a decision.

Every minute, every hour, every day that you sit around trying to decide, someone is already there.

"Make a choice or a choice will be made for you."

A cleaner makes decisions because there is no chance in the world he's going to let anyone else make a decision for him or her... It's just too risky.


" When you are a cleaner you don't have to love the work, but you're addicted to the results"

A cleaner's attitude can be summed up like this.

"He or she walks in with confidence and leaves with results."

Decide. Commit. Act. Succeed. Repeat.

  • A cooler is liked.

  • A closer is respected.

  • A cleaner is feared and then respected for doing exactly what everyone feared he'd do.

Cleaner’s Mentality.

"Let them judge me by my results. Nothing else."


“You never know how bad you wanted it until you get the first bitter taste of not getting it, but once you tast it, you're going to fight like hell to get that biterness out of your mouth.

A cleaner knows when to walk away. He can lose a battle because he's still planning to win the war. Lose a game, but win the season. Lose a season, come back and win the next three. Lose a job, start a business.

"No one else is getting the last word on whether he or she succeeded."

Successful people compensate for what they don't have; unsuccessful people make excuses, blame everyone else, and never get past the deficiencies.

Relentless is about achieving the impossible. Being relentless means demanding more of yourself than anyone else could ever demand of you, knowing that every time you stop, you can still do more. You must do more.

"Physical dominance can make you great. Mental dominance is what ultimately makes you unstoppable."


  • "Being relentless means demanding more of yourself than anyone else could ever demand of you, knowing that every time you stop, you can still do more. You must do more. " - Tim S. Grover

  • "True relentless people–cleaners are predators, with dark sides that refuse to be taught to be good. And whether you know it or not, you do have a dark side. Use it well and it can be your greatest gift." - Tim S. Grover

  • "A cooler is liked. A closer is respected. A cleaner is feared and then respected for doing exactly what everyone feared he'd do." - Tim S. Grover

  • "A cooler makes you wish you paid him less. A closer asks how much and then decided how hard he'll work. A cleaner doesn't think about the money; he just does the work and knows you'll be grateful for the privilege of paying him." - Tim S. Grover

  • "A cooler wonders what's going to happen, a closer watches things happen, a cleaner makes things happen." - Tim S. Grover

  • "A cleaner never sees obstacles or problems, only sees situations in need of solutions."

  • “In order to have what you really want, you must first be who you really are.”


  • 1) Ask yourself honestly, what would you need to sacrifice to have what you really want? Your social life? free time? Now answer the question: What are you willing to sacrifice? If those two lists don't match up, you don't want it bad enough.

  • 2) Get comfortable being uncomfortable, or find another place to fail.

  • 3) Make everyone else get on your level; you're not going down to theirs. You're not competing with anyone else, ever again. They're going to have to compete with you. From now on, the end result is all that matters.
