In honor of Worldwide Invest Better Day, we at The Motley Fool are recapping our "13 Steps to Investing Foolishly" — steps you can follow to become a better, more Foolish investor.

While savings accounts and money market funds usually fail to even keep pace with inflation, with enough patience, stocks can be a powerful wealth multiplier.
