The author shares a simple, high-compounding habit: using AI to maintain a "decision journal."

The process involves taking a few minutes during major decisions to log what was decided, the reasoning, expected outcomes, concerns, and what would prove the decision wrong. The real value lies in retrospective reviews—pulling up past quarters' decisions every few months to compare initial expectations with actual results.

Through this, the author identified personal biases: consistently overestimating timelines, worrying about the wrong issues, and underestimating the time needed to align stakeholders. They note that such feedback is rare in a career, and AI helps by making it easier to consistently record messy thoughts and retrieve them for pattern summarization.
