That's fair. The place most people are coming from when they start a business is usually that their idea is "brilliant" or "world-changing". Some ideas are better than others and most aren't as good as people think they are. Yet, even if the idea is actually brilliant, it doesn't matter at all without execution. Even the brilliant ideas will eventually change quite a lot during the execution of product / market fit to find those first few customers who will actually pay you money. People would be best served by convincing the first customer to buy something that actually doesn't even work and is just a webflow of what could be. Ask them what they want changed and promise to do that and then and only then starting making what they have agreed to buy.

Yes, my original post was not verbose, but I think people are better served by hanging signs all over their start-up that say what I wrote. Ideas are fun, ideas are hopeful, ideas can be magic, ideas can fill your heart but success comes from out-working everyone else. I have several truly great company ideas but I've never started them because I know in my heart that I don't want to go do all the work required to make it success.
