Can you find a solution to your problem that will make a meaningful impact in a reasonable time frame? ### People are willing to pay for solutions You spoke with the people struggling and they confirmed, yeah, this is a problem for me and, yeah, I’m willing to pay for a (better) solution. ### Your problem is a precise statement You can describe the problem you’re seeing in terms of what it is, why it’s happening, to whom, and how it impacts them.
