You might have an idea of what a market wants, but you won’t ever truly know until you put your work out there and see if the market bites.
You can put out feelers, demos, and trials, but in the end, what only matters is what will come after that work.
What you might find is that you have to build your market, and that might be the trickiest scenario of it all, because then you’re putting something out there, hoping others want and need it as much as you do.
Factor in that so many markets are now splintering into an infinite number of niches and changing day to day, and you have to wonder why anyone would bother.
Because it’s the best challenge there is.
