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.
Having a business plan is so important to you as an online marketer. But most people, who start online businesses, especially small businesses, do not really take the initiative to make a business plan. Probably they think that it's not necessary. But for sure there is little you can achieve in life without proper planning. More so in the contemporary times when survival depends largely on one's ability to organize your physical and mental resources well. The future is actually for those who are organized. And the future of your business is dependent on your good planning.
