Have you ever owned a business? You must have training in the business you want to start. If you want to have a resturant, it is best that you have worked in resturants and understand all parts of the business. You should also have enough money to live on for 2 years until the business becomes profitable. Start small and build. There is much more to learn, and Feng Shui can only do so much.
Good luck in your adventure.
