It takes money to make money.
How many times have you seen that repeated on marketing forums?
Guess what?

That's a big fat lie!
9 times out of 10, the person saying that is trying to sell you something.  That's not a bad thing - after all, that's business, right?
The problem with that is we don't all have the cash to invest hundreds and thousands of dollars into our business.  When I started out, I didn't have anything to invest.  Heck, I was trying to make some extra income just to pay the bills every month!
