The old saying that the rich get richer is very true. As long as you manage your money well, it's far easier to make money if you've already got some cash socked away than it is to start from scratch. The reason is simple: compounding.

When you've already got money working on your behalf, each percentage point of return simply adds that many more dollars to your account balances. After all, if a stock you own goes up in value, it's far better to own 10,000 shares than it is to own 100.
