Instead of find new problems needing solutions, I would flip it around and find more solutions to the problems you have had or things you had solved. Coming up with more ways to solve the same problem can be a very creative process and lead to a lot of ideas. Subcategorizing your problems, and then finding more efficient solutions to these subcategories might also be helpful. You might be generalizing your solutions to address more and more potential problems that crop up, and while it will eventually solve the issue at hand, there may be more efficient or creative solutions. Many ideas end up becoming, we solve x, but better than y ever managed to for z. AirBNB solved the finding a place to stay even though hotels already existed. Same for Uber. We have endlessly improved upon wheel designs for millenia. The possibilities are endless.
