I think asking some basic troubleshooting questions is helpful.
Is your product worth paying for? Is it even worth someone’s time to look at it or download it for free?
Is it the type of thing that you yourself have paid for in the past? (E.g. if you’re making infographics about cooking, ask yourself, when’s the last time you gave someone money because of their cooking infographics). Would you pay for your own product?
If you can’t imagine a scenario where you would pay for your own product, then why would anyone else?
