Small scale business ideas

I have been always aspiring to do my own business and get money out of it. In short, I want to be my own boss and be the CEO of my company. I was thinking of various options. As I will be a start up entrepreneur, I thought it will be best to read articles that will first help me understand the ground reality. I realized that i need to be prepared with many things before I start off. Firstly, the place that I will require for my business and so on and so forth. You need to define your business' USP (Unique Selling Proposition) and that should be key differentiators for your business compared to your competitors. I am deeply thinking of what business to take on and what should be the USP of my business.
