"Execution is everything" is unfortunately tautological in that it implies you first reach success, then you measure the execution and idea. It leaves no escape-hatch to judge that an idea is bad. And bad execution can only be spotted if somebody else does good execution. Similar to saying a startup needs to get product-market-fit to get success. Success defines that you have product-market-fit. We are all horrifically bad at thinking about cause and effect, or talking about it. But yes, I've slowly learnt that doing anything often matters more than a grand idea.
