I interviewed 50 founders. Here's the #1 trait they all share.

It's not resilience. It's not vision. It's not even intelligence. It's speed of learning. Every successful founder I spoke with had one thing in common: they could take feedback, process it, and implement changes faster than anyone else. They didn't wait for perfect data. They ran experiments in days, not months. The startup graveyard is full of brilliant ideas executed slowly. Speed of learning > speed of execution. Because you can't execute on the right thing if you haven't learned what the right thing IS.
