That means I would have to decide what kind of business to start.
If I decide to sell things I'd have to locate a supplier and place an order or make something myself.
If I decide to offer a service I'd need to think of something I can do that people might wish to pay for. I might even need supplies of some sort.
I'd need to make a sign to put outside my door, or rent a place, and maybe advertise as well.
I doubt I could be open before tomorrow evening with so many things to consider and get done. Oh, the pressures and stresses inherent in freedom! (wink!)
