From mailman to CEO

One way to know whether you’re on the right path with an idea or not is to know its history.
Is there a history where somebody made your idea (or similar) happen? Is it possible?
This is a great reality check. It’s like a mailman from a Fortune 500 company who wants to be the CEO. It won’t happen. There’s no history of that happening in the past, so that person better focuses on something different (prove me wrong, please!)
Nevertheless, if what you do has been done before, you’ve got proof you’re on the right path.
Of course this is not the way to get a big breakthrough or the famous 10X thinking, where you need to start with a blank slate. But more often than not, it helps.
Being first doesn’t matter that much, though.
