In 1913, J. N. Muncey of Jessup, Iowa, showed that the first 144 odd prime numbers (counting 1 as a prime, as was sometimes done historically) can be arranged into a magic square.

Each row, column, and main diagonal has the same sum: 4514.

"It's a daily process. You just stack good days. Everything we do we have high standards and expectations. The standards can never be compromised and there has to be accountability throughout the entire organization coaches and players." - Curt Cignetti

The scoreboard doesn’t care about your intentions.
Your competitors don’t care about your excuses.
And your potential doesn’t care about your promises.

So here’s the question:
Are you committed to the process… or just attached to the outcome?

Talk is easy.
Do the work.

Behind every state championship banner is a group of kids who learned that mediocrity doesn’t cut it, accountability is earned, and success is shared. Winning is just the byproduct.

“We don't become you. You become us."

Great teams don’t adapt to individuals.
Individuals adapt to the standard.

The culture is built.
The standard is set.
You either buy in, or you don’t belong.

“It’s a process. It’s a way you go about doing things. It’s a high standard, high expectation, it’s accountability. It’s discipline, commitment, toughness, work ethic, pride. It’s wanting to be great vs. wanting to be normal,” Curt Cignetti

The difference is within you.

[Coach Dan Casey @CoachDanCasey]

Accountability starts with self-reflection.

“We’re going to reach our full potential, but there’s going to be some pain. You’ve got to go through it.”

Hot take: we should teach proofs in high school mathematics

You don’t “turn it on” at 7PM under the lights.

You turn it on at:
– 6AM lifts
– Class on time
– Extra indy after practice
– Film when nobody’s watching

Game day just exposes what you built Monday–Thursday

If you feel pressure, it means your life is big, your goals matter, and you're standing in the exact spotlight you used to dream about.

“Too many kids today are afraid of failure.” - Doug Collins

Failure isn’t the end. It’s the lesson.
It’s how you grow, learn, and get tougher.

Every champion has failed; they just refused to stay there.

[Greg Berge @GregBerge]

Culture isn’t built in the big moments.

It’s built on the random Tuesday.

- How you start practice
- What you tolerate
- Who you praise
- The standards you enforce when nobody’s watching

The little things?
They’re the big things.

George Boole was born exactly 210 years ago today. He was largely self‑taught, the son of a shoemaker, yet founded what we now call Boolean algebra.
