Master Yourself First: Leadership Lessons from the Ivy League

A recap of our August PoShe event with Marian Cook

Before you can lead a team, a business, or a room full of people, there is one person you have to be able to lead first, and that is yourself. That was the heart of our August gathering, when Marian Cook of Archstone Workspace brought her Ivy League leadership work into our room for an honest, working conversation about the inner game of leading well.

Marian teaches this material to graduate students at Yale and MIT, but there was nothing academic about the way she delivered it. She made us work for it, she made us laugh, and she sent everyone home with something to actually practice. For those of you who were there, consider this your set of notes to reflect back on. For those who couldn't make it, here is what you missed, and why we hope you'll catch her the next time around.

The evening moved through three ideas that tend to get tangled together in real life: mastering yourself, testing your ideas, and finding your advisors.

The first person you lead is yourself

Marian opened with the part of leadership nobody warns you about. It is not the difficult client or the resistant team member that trips us up most often. It is our own reactions. She walked us through what happens in the body when we get triggered, the voice that climbs a little higher, the breath that quickens, the sense that we are quietly bracing for a fight. The skill, she said, is learning to notice that activation early, because a leader who catches it has far more choices than one who only realizes it after the damage is done.

She had a wonderful word for the moments we don't catch in time. She calls them "wincibles," the exchanges we replay later, wishing we had handled them differently. The goal is not to eliminate them, because we are human, but to reduce how often they happen by pausing before we react. She reframed self-awareness as performance infrastructure, a leadership skill rather than only a wellness practice, and that reframe alone was worth the night.

"Emotional regulation is not suppression. It is recovering the ability to choose."

The practical tool she left us with was a simple pause: notice what you are feeling, name the trigger, narrow in on what actually matters right now, and then choose the response that fits the leader you want to be. She also reminded us to extend ourselves some grace, noting that women in particular tend to be far too hard on themselves.

Progress beats perfection

The second idea was aimed squarely at the perfectionists in the room, and there were a few of us. Marian's antidote to being stuck is a phrase she comes back to again and again: it's just an experiment. When the path forward isn't clear, you don't need a finished plan and you don't need to bet everything at once. You need the smallest useful test that will teach you something real.

She gave us grounded examples that any entrepreneur can use. Thinking about a partnership? Don't sign a contract on day one, co-host one event or create one piece of content together and see how it feels. Dreaming about writing a book? Blog your way toward it and build an audience while you learn what resonates. Wondering whether the market wants what you're building? Put a small version out into the world and let the response tell you, instead of talking yourself in circles.

"Ideas are easy. Execution is brutal."

Her point was that experimentation is disciplined progress, not random guessing. A good test makes your assumptions visible and treats failure as information rather than defeat. And as she put it, borrowing a line many of us recognized, you don't need to know step five. You just need to know the next best step.

Do not lead alone

Marian closed with a caution that landed with a lot of us: isolation distorts your thinking. When you only talk to yourself, or only to people who already see the world the way you do, you lose the ability to tell fear from fact and reaction from priority. The answer is to build a personal board of advisors, not just a network, and to be intentional about filling it with people who think differently than you do.

She broke the board into five distinct seats, each one offering something you cannot generate alone. There is the Truth Teller who gives you candor and reality checks, the Possibility Expander who brings fresh options and imagination, the Calmer who offers perspective and steadiness, the Strategist who helps you see patterns and tradeoffs, and the Encourager who brings belief and courage when yours is running low. She asked us to look honestly at which seat sits empty, which is overused, and which is filled by someone a little too similar to us

One more piece of wisdom worth holding onto: when you gather feedback, be careful about relying only on the people who love you, because they want you to succeed so badly that they may not tell you the whole truth. Real advisors give you candor, judgment, and perspective, and then you listen widely and still own the final decision yourself.

From stuck to strategic

The through line of the night was practice over perfection. Steady yourself, test your way forward, and stop trying to do it all alone. Marian asked everyone to leave with one concrete action they could take within forty-eight hours, small enough to actually finish and meaningful enough to matter. If you were in the room, this is your gentle nudge to go do yours.

Thank you to Marian for a generous, practical evening, and thank you to every one of you who showed up for yourselves and for each other. This is exactly the kind of conversation this community exists to have.
