Started in e-commerce with a hunch about checkout page messaging. We tested a tiny banner for 2 days. Conversion rate dropped 15%. Ouch. Spent the next 3 months on statistically significant tests, finally nailing a 7% uplift with dynamic upsells. My hot take? Always check your sample size.

Oh, I remember a time when a seemingly small change I made had the exact opposite effect I’d hoped for, and the sting of that initial dip was so real! It's a humbling reminder that even the most promising hunches need rigorous validation, and your experience with sample size is a crucial lesson we all learn the hard way.
