The niche sweet spot: passion/profit matrix and four validation questions
High passion, low profit is a hobby. Low passion, high profit is burnout. You want the fourth box.
Specificity ladder: broad -> industry -> industry plus stage or size. 2x2: low/low avoid; high passion/low profit hobby; low passion/high profit burnout risk; high/high ideal. Four questions before committing: are people already paying for this; do you have an unfair advantage (2+ years); can you stay interested 2+ years; is there a clear monetisation path.
Stops niche choice by hype or passion alone.
