# Product Market Fit

## Overview

Mindset skill for product market fit. Builds capability through deliberate practice and structured frameworks.


## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "I'll figure it out as I go" | A structured approach saves time and reduces errors. Follow the workflow in this skill rather than improvising. |
| "I already know this topic" | Familiarity breeds shortcuts. Use the checklist to verify you haven't missed critical steps. |
| "This doesn't apply to my situation" | The patterns here generalize across contexts. Adapt, don't skip — the underlying principles hold. |
| "One more tool will fix it" | Adding complexity rarely solves process gaps. Master the core workflow first. |

- Pre-PMF: validating a new product

3. **Evening reflection** — Review the day's product market fit moments and lessons learned
4. **Journal entry** — Record insights, wins, and areas for improvement

## Frameworks
