You can have a great startup idea, but a great startup idea is like having a great plan for a fistfight. 

The moment the idea actually touches customers is like the moment you get punched in the face.

What matters is what you do at that moment, not the plan.

punch your customers in the face, got it

will report back

Are these customers in the room with us right now?

Execution 98%, Idea 2%.  You need a decent idea, but even mediocre idea often outcompete amazing idea simpy by executing.  Salesforce, e.g., is built upon that very thing.

I get the metaphor and agree with the emphasis on praxis though SaaS is, uh, not entirely comparable to physical combat along the primary vectors of interest

In this parallel, I wonder how founders could train to develop proper conditioned reflexes
