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!
Besides, your friends may be 100% behind you in your new venture, but, in case you are hoping to involve others who have actual money to invest, you may need to be able to make a convincing case. Wouldn't it be nice to have anticipated possible questions and be ready with plausible answers? If you are risking your own money, that is perhaps even a stronger reason to do some indispensable planning.
