Build a YouTube channel around extreme skill-acquisition or access challenges (e.g., earning a black belt in 90 days, training with elite units) modeled after Michelle Khare's 'Challenge Accepted' format, which amassed 6 million followers and 1 billion views. Revenue comes from AdSense, sponsorships, and brand deals. The defensible moat is the insane barrier to entry — producing 8–10 high-quality episodes per year rather than chasing upload frequency.
