I will not promote, M19 - After long preparation I am seeking guidance on building my first legitimate start-up

I'm 19, the oldest of 4 in a low-income, single-parent household. After working 13 jobs, I’ve saved enough to commit a year to building a startup full-time.

My biggest roadblock: identifying a real problem worth solving. I understand that solutions in search of problems fail, so I’ve spent the last month trying to talk to businesses—cold emails, calls, in-person visits—hundreds of attempts, almost zero useful responses.

I know the best startups solve real pain points, ideally B2B, but I can’t even get in front of decision-makers to ask what their problems are. How do you actually get businesses to talk to you? If you were in my shoes, what would you do to get the ball rolling?

I’ve studied all the Y Combinator advice and know I need real people with real problems—but getting access to them is proving nearly impossible. Any advice on practical next steps?
