Although scratching your own itch is sound advice, it's difficult to assess whether's the market size is just you. I recommend being lazier on the finding the problem part since most problems already exist and the variety of solutions just address them. The real innovation and value proposition when building something is whether your solution has the ability to overcome the friction and displace a meaningful segment of the market. This can be a innovation in distribution, performance, scale, cost, etc. All problems are real. The question is whether they are real to others and how real you can make the solution for someone other than yourself to use it.
