Being good at making other people money is actually a skill you can monetise. That’s basically what B2B software is: making money for other people. It’s the very definition of value creation. So focus on how you can make money for other people, then scale that up in a way that allows you to charge less than the value created but more than the cost to produce.
Also don’t try to think of an idea, just start talking to business owners about problems that cost them money or constrain growth (opportunity cost) and fix those problems.
