How is that Working for You?

To borrow a line from Dr. Phil, How's that working for you? I see a lot people speaking of multiple income streams, but how many are actually making it work? Do you have multiple incomes or just multiple outgoes? I would suggest that it is better to focus on a single primary business, and if you happen to make a few bucks on other sites, then it's just a small bonus. Just throwing that out there as food for thought. Bill
