You're good at your job. Else you probably wouldn't be a Staff Engineer, a Tech Lead, or a Senior People Leader.
But something happens when you walk into a room with your skip-level or a cross-functional review with people 2 levels above you.
You talk too much. You explain things nobody asked about. You hedge. You get pulled into technical detail because that's where you feel safe. You walk out and think: I know my stuff. Why can't I land it?
You're not bad at communication. You're bad at communication under certain situations, especially in rooms where the stakes feel high and the power dynamic is stacked against you.
That's what this is about.
In 1936, a psychologist named Kurt Lewin wrote a simple equation.
B = f(P, E)
Behavior is a function of Person and Environment.
Side note: The person is a function of nature, nurture, shared and non-shared experiences, effort to reflect and give oneself agency and several other factors. More on that in another section.
Since B = f(P, E), it means how you act isn't just about who you are. And it isn't just about the room you're in. It's the interplay between the two. Change either one and the behavior changes.
This is why you can be brilliant in a 1:1 with your manager and fall apart in a skip-level with a VP. Same you. Different room. Different behavior.
Lewin's equation is almost 90 years old. Nobody has replaced it.
The Executive Presence Equation has 4 layers. These layers work like a symphony, each one called to the forefront when the moment demands it, like the right service being called by a well-written API. When it works well, it looks effortless. But that fluency is itself a function of awareness, practice, reflection, and adjustment.
The P in Lewin's equation.
Before you can show up well in any room, you need to know what you bring into it. Not your resume. Your patterns.
