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.

In the following video, Dayana Yochim recaps Step No. 3: Treat every dollar as an Investment. An investment is more than just something you make in your brokerage account; it can just as easily be an investment in a guilty pleasure, such as your daily Starbucks treat. But if you think about every single dollar that leaves your hands as an investment in your short-term, mid-term, or long-term future, chances are you'll make more prudent decisions. Heck, you may even decide to buy a few shares of said coffee purveyor and forgo a few short-term drinks in place of long-term wealth -- but that's for you to decide.
