McChrystal reduces character to a deliberate equation: character equals your convictions multiplied by the discipline to live up to them. Convictions are not the superficial things you accept because someone told you and never checked; they are the beliefs about life and values you have deliberately examined, red-teamed, and decided you would live or even die for. Most people never do this work, defaulting to the religion, patriotism and opinions they were first exposed to and passing them off as their own. The second term, discipline, is self-discipline: the ability to get yourself to do the things you have decided you should do, especially when tired, impatient or angry. The equation is a lifelong project. You are simultaneously discovering exactly what you believe and building the discipline to live to that standard, the way a Stoic acts a certain way simply because it is right.
Origin
McChrystal's own formulation, stated in the interview: he says he brought character 'down to a mathematical equation' of convictions and the discipline to live up to them, drawing on Stoic thinkers like Marcus Aurelius.
Core principles
- 01Character is not innate; it is developed through examined belief and repeated practice
- 02A belief only counts as a conviction once you have red-teamed it yourself
- 03Discipline is the ability to make yourself do what you have decided you should do
- 04Values without the discipline to live them are just opinions
- 05The test of character is holding personal lines when crossing them would advantage you
How to run it
- 1
Surface your real beliefs
Separate the beliefs you have genuinely adopted from the ones you inherited by default from parents, nationality, or influencers and never questioned.
Watch out Most people are simply the religion and politics they were first exposed to; assume many of your beliefs are unexamined.
- 2
Red-team each belief
Force real opposition onto each belief. Argue the strongest case against it and decide, honestly, why you still hold it.
Pro tip A belief that survives you attacking it becomes a conviction; one that does not was never yours.
- 3
Keep only load-bearing convictions
Retain the beliefs important enough that you would live for them, or if necessary be willing to die for them. Discard the rest.
- 4
Build the discipline to live them
Develop self-discipline: the ability to make yourself do what your convictions require, particularly when you are tired, impatient, or angry.
Pro tip Practice small, unglamorous disciplines daily so the standard becomes who you are, not a performance.
- 5
Draw and hold your personal lines
Define the lines you will not cross for advantage, and hold them precisely when crossing them would get you ahead. That moment is the real test.
Watch out Flexible personal lines under opportunity are how good character drifts into bad; this is where most people fail quietly.
In the wild
McChrystal still folds his underwear in his drawers and gets up to work out on a fixed standard, habits others laugh at. He treats these small, self-imposed disciplines as reps: doing certain things to a chosen standard simply because he decided to, which over decades has served him well.
→ Mundane daily disciplines compound into the consistency that separates him as a leader.
McChrystal notes most people hold the religion their parents raised them in and are patriotic simply because of where they were born, never doing a comparative analysis. A conviction, by contrast, is a value you deliberately reflected on, forced opposition against, and chose to stand on.
→ The difference between borrowed opinions and owned convictions that can actually anchor behavior.
Common mistakes
Mistaking inherited beliefs for convictions
Passing off first-exposure beliefs as your own without ever red-teaming them means you have opinions, not convictions, and they buckle under pressure.
Bending personal lines for advantage
Keeping the discipline visible to others but quietly pushing aside personal standards when it profits you is the drift from character into bad character.
Is it for you?
Best for
Anyone wanting to define who they are and develop the self-discipline to actually live it.
Not ideal for
People seeking a quick external win rather than a long-term identity project.

“I brought it down to a mathematical equation. It's what are our convictions, the things we believe in that we've really pressure tested, and then…”
“Self-discipline is the ability to get yourself to do those things which you believe you should do and you decide to do”
