Progress Check: How To Know If You're Actually Changing or Just Thinking About Changing

Eight weeks after receiving a structured PMF diagnostic, most founders can articulate their key findings with real precision. They can name the patterns, explain the mechanisms, identify what they've been avoiding. What's harder to demonstrate is behavioural evidence that anything has actually changed. This gap — between an updated self-narrative and updated behaviour — is the most common failure mode in founder development work. You haven't changed because you've updated what you believe about yourself. You've changed when your decisions in the following eight weeks consistently differ from your decisions in the eight weeks before. The measurement that matters isn't your self-assessment. It's the decision data.
