I was gonna post my actual matches from today. 
But then I watched them and realized this was much more entertaining.

Big thanks to an awesome opponent Lawrence Borja. Couple of dads just trying to get ready for Master Worlds. Super thankful for the brown belts who show up!

He’s 6. He cannot sit for eight hours.
Neither can you.
Sitting still is not a subject.
So we changed the room… not the boy.

Reading. Writing. Math.
That’s the floor.
Not the ceiling. 
Nobody’s whole life fits on a report card.

Can your child think for themselves?
Can your child lead a room?
Can your child talk to an adult, look them in the eye, shake hands?

We’re not comfortable with an educational system that we believe prioritizes conformity over individuality and independent thought. 

At the end of the day, education is the greatest investment you can give yourself. No one can take away your growth, your confidence, or the person you become.

Core curriculum is the floor. Apogee is shattering the ceiling.

Everyone asks what’s in the red syringe. So here’s the whole shelf.

I’m not telling you to run what I run. I’ve been doing this a while and my protocol comes off my bloodwork. What I can do is give you a starting point. Answer some questions about your symptoms and goals, get a list back, then go get labs and talk to somebody who knows what they’re looking at.

Comment PROTOCOL and I’ll send it over.

Disclaimer: if the label says for research purposes only, not for human consumption, don’t buy it. It’s cheap for a reason and you have no idea what’s in the vial. Only two certified sources exist and we use both. Bloodwork and a provider before anything else.

I think there might be something here. It takes a special kind of person to pick something that you're just gonna suck at forever. I don't know. What do you guys think? Is there a pattern that's happening here? 😂

Two lawsuits right now. Neither one is from a customer.

Both are from people who entered a giveaway, got a confirmation text saying they entered, never bought a single product from us, and then went looking for a payday. The California one cost us an enormous legal bill and ended with about a hundred dollars in her pocket. Florida is running the same play.

Here is who that money comes from.

Retired Marines. Former law enforcement officers who left that career for a better life. Mothers supporting children and their own parents. People who just bought their first house. Guys working their first real good paying job. A man who started in our lab and worked his way up to running manufacturing.

Not a Fortune 500 that can print its own money. A small American manufacturer in North Carolina that makes its products across the street from this building and pays above the national average on wages and benefits because ownership decided that mattered more than margin.

If we did something wrong, come get us. You got a text confirming a giveaway you signed up for. That is not harm. That is a scam with a case number.

If you do this to people, you should be ashamed of yourself. Go get a real job. Go earn something instead of trying to take what other people built.

Very honored to have this incredible individual in my life. 
Thank you for another awesome year. 

If you want to get better at anything, be in rooms where you are not the best one there.

I got my third stripe on my brown belt this week. Black is next. But the day before, I trained with only black belts and left feeling like I had made no progress at all. Like my jiu-jitsu did not work.

That was the feeling. It was not the truth. The next day I earned three stripes.

Here is what I want you to take from that. When you surround yourself with people who are better than you, you are going to feel behind. You are going to feel like you are not improving. That discomfort is not a sign you are failing. It is the cost of being somewhere that will actually make you grow.

The men who quit are usually the ones who mistook that feeling for the facts.

Stay in the hard rooms. Let them stretch you. Your progress is real even on the days it does not feel like it.

Massive congratulations and thank you from the bottom of my heart to the CEO of @coremedhrt , @sjgcore , and his tireless effort in supporting the veterans of this nation and all the entire team at Core Medical. I can't thank you guys enough for what you've done. This is going to be a massive, massive shift in saving men's lives, and I recognize the sacrifice that they took and the hard work it took to get there.

Successful men are killing themselves and everyone acts shocked.

Great dad. Big deal at work. Vacation last month. Gone.

Here’s what nobody says. We don’t get a pass. We bury it until it buries us. Stressed, angry, lonely, tired, yearning for more, and too proud to say a word.

You are not a special butterfly. Every man is carrying it. Most just do it in silence until the silence wins.

The goal is not a slightly better life. It’s a life you don’t need to escape from.

You are on the meds. You are doing the work. And you still do not feel like you.

At some point you have to ask a harder question: what if the problem was never fully in your head?

Testosterone drives mood, focus, sleep, and drive. When it bottoms out, it looks exactly like depression. Same symptoms, different cause, completely different fix. Most men are never tested for it before they are medicated for it.

We are not telling you to stop anything. We are telling you to find out what your levels actually are.

Comment CORE and we will run the bloodwork to see if this is your missing piece.

Secret to good morale? Communication. 

He communicated he could take me. I communicated back. 

Let him feel important for a second, then made him tap with a smile. 

Morale around here is at an alltime high. Mine, specifically. Through the roof. 

Couldn’t tell you about his. But mine? Best it’s been in years. 

Great culture here at @johnnyslicks

Cleaning house. 

Today is June 29th.

Tomorrow it’s June 30th, and I’ll make the same decision I made today. Then again in July. Again in August. Every morning after that until I physically can’t.

50 push-ups. 20 pull-ups. Time on the mats. A clear head. No numbing it. No outrunning it.

I already met the man who quits on himself. Lost a marriage to him. Lost my body to him. Almost lost my kids to him. I don’t let him drive anymore.

The work doesn’t get easier at 44. You just stop expecting it to. Get up. Get after it.

Reclaim the Man within a Marine Raiders framework for men done drifting. Launches Father's Day, June 21st.

You guys said you wanted an audiobook, and I'm doing an audiobook and I'm reading it myself. 

Much appreciation for the people out there that do audiobooks and read, and for the man who read my audiobook, "Excommunicated warrior", because this is way harder than I thought. 

Nonetheless, I'm enjoying it. It's a great process. I'm looking forward to getting it all packaged together and sharing it with you guys. 

I'm enjoying the book even more by reading it than I did writing it. 

Comment "PRESALE" and I'll send you the link.

Strength is the foundation every other part of your life is built on.

When you’re weak, everything else crumbles. Your relationships suffer. Your work suffers. Your ability to show up for the people counting on you gets compromised.

That’s why we train. Not for the mirror. For the man you become when strength is non-negotiable.

Go one more. Then go again.

Five minutes.

Years of jiujitsu fold into five minutes. Every private lesson. Every early morning. Every round where I got smashed and came back the next day anyway. Every drill, every rep, every hour I chose the mat over comfort. All of it compressed into 300 seconds against the number one guy in the world in my bracket.

Didn’t go my way. 4-0.

Here’s the part that stings…. I felt good going in. Best mental state I’ve ever had. Focused, present, aware. No anxiety, no noise. Exactly where I wanted to be. That’s probably why I’m pissed. It wasn’t nerves. It wasn’t preparation. I showed up as the best version of myself and still came up short.

But that’s the deal you sign when you compete. You put years on the line for five minutes against the best in the world, and you live with the result. He didn’t finish me. And I’ll be back. The work continues.

See you in September… 👊🏼

There is a version of you that you buried somewhere between the last deployment, the divorce, the weight, and the silence.

Reclaim the Man Within is the map back to him.

If Excommunicated Warrior was me telling you how I fell apart, this one is me telling you how I got back up. It is the next step. Same honesty, more blueprint.

I have been getting flooded with messages asking if there is a paper version. There is. It drops June 21st, Father’s Day. No accident.
