Investment Tip!

One thing to keep in mind about compounding interest is that the amount of money you invest follows the same rules no matter if it's $1,000 or $1,000,000. The U.S.A and world market size is so large that going from $100 to $200 is the same as going from $100,000 to $200,000 or $10 million to $20 million!! You have to start small and start now to get into the habit of investing!

** (Unless you're investing with a LOT of money (think 100s of millions of dollars) then the liquidity and market size is not a factor).
