I wonder if it is misleading to frame every startup as an attempt to solve a problem. That method would eliminate most industries of entertainment as a viable business. Another caution is the technology adoption threshold. Many times new technology incurs more painful adoption than the current optimized local maximum, early electric cars come to mind as an example.
I tried for years to think of business ideas by removing “pains” in my life. I never had any good ideas using that method. I think to find pains, you must first try to find a drive to change something in the world. That drive could be intrinsic or borrowed from another person/company/organization. After the drive/vision is found then all roadblocks/pains become a goldmine for new business ideas.
