I would like to start my own cram school for school children. However, my spouse doesn't understand it at all.I am not sure how I can get his cooperation. I think it is necessary that I need his help and cooperation for my dream. Although I want to use a room in my house, he doesn't like it. The first step to get his convince, I need to draw a business plan. How I can sucess, no risk which I lose my money.
