The $67,000 Mistake That Changed Everything
📊 BRUTAL TRANSPARENCY AHEAD Story time, entrepreneurs... 2 years ago, I made the most expensive mistake of my life. And it led to discovering the pattern that's now helping thousands of founders avoid the same trap. The Setup 🎭 The Idea: AI-powered fitness coach for busy professionals My Confidence Level: 11/10 (yes, eleven) Market Research: 23 hours (I thought I was thorough) Investment: $67,000 and 14 months of my life The "Validation": - ✅ 847 people said they'd "definitely use it" - ✅ Found 23 articles about AI fitness trends - ✅ Only 12 direct competitors (seemed low) - ✅ Fitness market = $96 billion (huge opportunity!)
