The first of the four areas: a great idea. It's become popular in recent years to say that the idea doesn't matter. In fact, it's uncool to spend a lot of time thinking about the idea for a startup. You're just supposed to start, throw stuff at the wall, see what sticks, and not even spend any time thinking about if it will be valuable if it works.

And pivots are supposed to be great, the more pivots the better. So this isn't totally wrong, things do evolve in ways you can't totally predict. And there's a limit to how much you can figure out without actually getting a product in the hands of the users. And great execution is at least ten times as important and a hundred times harder than a great idea.

But the pendulum has swung way out of whack. A bad idea is still bad and the pivot-happy world we're in today feels suboptimal. Great execution towards a terrible idea will get you nowhere. There are exceptions, of course, but most great companies start with a great idea, not a pivot.

If you look at successful pivots, they almost always are a pivot into something the founders themselves wanted, not a random made up idea. Airbnb happened because Brian Chesky couldn't pay his rent, but he had some extra space. In general though if you look at the track record of pivots, they don't become big companies. I myself used to believe ideas didn't matter that much, but I'm very sure that's wrong now.
