I'm not saying you can't or wont' succeed. I have no idea.
But it seems like the first thing that happened is that you decided you wanted to start a business. Usually it's the reverse - you get inspired by discovering a problem and realize you have the skillset and motivation to solve it and then you come to the realization that you need to start a business to do that. For founders/entrepreneurs with experience having done that previously, this is likely a scenario with a much higher probability of success.
But I imagine the success rate of people who say "I want to start my own business" and then look for a business to start have much lower success rates.
I'm not trying to rain no your parade at all. Just wanted to give you something to think about before you spend a fortune in time and/or money starting something. I could easily be wrong, though. Just food for thought.
