Biggest mistake of people learning trading.

Everyone in trading has that “ouch” moment. Chris Dunn breaks down why those painful trades are actually goldmines for learning. The same idea applies to marketing. Your failed campaigns can be your best teachers—if you know what to look for.

Marketing Analysis

When you bomb a campaign, don’t hide it. Study it. Figure out the weak link: offer, targeting, message, or timing. Traders call it a “post-trade review.” Marketers can do a “post-campaign review.” Same goal—learn fast, lose less, win more.

Why It Works

• Treats failure as feedback
• Builds better instincts through repetition
• Makes data your decision-maker, not ego
• Encourages quick experimentation cycles

Examples

• Coca-Cola learned from “New Coke” and doubled down on classic branding.
• Airbnb fixed its early low-conversion problem by improving listing photos.
• HubSpot used failed ad tests to refine its targeting and drop CAC by 20%.
