It's an old saying that "It takes money to make money." Well ... while having a bit of money can HELP you multiply it (many times over), wealth for most people does NOT come from already having an abundant supply. Besides the course investment, you do not need to begin with any funds.
To make money, all it takes is a dream, and an IDEA ... you get it out of your head, onto a piece of paper, by writing out a description of it ... and before you know it, that (often very simple) idea turns into a definite plan to create wealth.
The light bulb, the pen, the smart phone, the automobile - Beanie Babies - LOL - these were all once just ideas that someone had, that they turned into billions of dollars of revenue.
You can do this. Take one step at a time.
