A failed experiment still hands you data. The only experiment that teaches nothing is the one you never ran.

An attempt that does not work still narrows the field. You now know one way it goes wrong, which is real information you did not have before and cannot get by thinking about it. The only move that returns nothing is the one you never make, because it leaves you exactly where you started while feeling cautious and sensible.

When something flops, spend five minutes writing down what you actually learned before you move on. What you expected, what happened, what you would change. That habit turns a run of failures into a set of findings, which is a much better thing to be carrying.
