The key is to save early and often. If you do, you'll have $500,000 before you know it.

NET GAINS UPDATE: Last month, I wrote about the warning the Financial Industry Regulatory Authority issued about debit cards linked to a 401(k) account that allow users to borrow from their retirement savings on a moment's notice.
Last week, U.S. Sens. Charles Schumer, D-N.Y., and Herb Kohl, D-Wisc., introduced legislation to ban 401(k) debit cards, which they called a "dangerous practice."
"These debit cards allow participants to use his or her retirement savings to make everyday purchases like buying a cup of coffee," Kohl said in a statement. "Clearly that's not what the 401(k) is for."
