How does the identity cost start?
You build something. The feedback is immediate and legible — revenue, recognition, growth, the satisfaction of a problem solved. That feedback feels good. It should. You're doing something real.
But founders are human beings with human needs — for meaning, for worth, for belonging, for a sense that what they're doing matters. Those needs don't disappear when you start a company. They find a home there.
Early on this is fine. The alignment between personal need and business activity is close enough that it barely registers. You're passionate. You're driven. You care. These look like founder virtues — and they are.
The problem develops slowly, invisibly, as the business grows.
