Yes most persons do not even have a back up for their business, they just have a business plan and that's all. It's not really a must to have one but this is just a percussion to have something to fall back to incase things do not go as planned.But even if this is necessary like you just said, most people do not really have a backup plan over here as I understand. a lot of people are just established their business and rely on that business alone... Don't you think so ?
