Before you spend money or make any plans for a business you must know what exactly you want to start or open. Without knowing that, moving forward is going to be virtually impossible.
Gee, that's looks like a failure already even before starting your business. In another thread, I had read that one way of failing is not knowing about your business. And the fact that you don't know what business to have means you need to evaluate your knowledge. Anyway, what I can suggest is a business that is directly related to your passion. That way, you will enjoy your business no matter what happens. For example, if your passion is the kitchen then you can open an eatery or a food delivery business. I hope that helps.
