It is a fact of life that any new business or enterprise has a degree of risk attached to it. Therefore it is important for your business plan to analyse and calculate that risk, showing how you will engage with it. There is no business plan out there that is risk_free, but very often where the risk is higher then the rewards will be as well.
As I conclude, I would like to advice all people, who want to start any kind of business or who already have business without a business plan, to think about creating one as way to building a successful business. One of the causes of failure in business is lack of proper planning. Create a business plan if you want to succeed in your online home business!
