Ask HN: How to find viable product or service ideas for small business

My objective is to work for myself and eventually turn that into a sustainable business, but I am having a hard time trying to figure out what exactly are the next steps in order to move towards my objective. My current perspective is one of trying to find a idea for a product or service as starting point. Do I need a different perspective ? or Just not thinking hard enough on what product or service to build ? Thanks for your help !
