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, analyst Austin Smith covers Step No. 7: buying your first stock.

While taking that plunge into investing can be exciting, it should also be measured. More than anything, your first stock purchase should be regarded as a lesson in investing, not the end-all-be-all or get-rich-quick move that many of us wish it was. Investing is a game that favors the patient, so when you're buying that first stock, don't jump in with both feet. Buy just a few shares and learn from that position. Follow the stock, learn to keep a cool head when it decreases in value, and become a better investor in the process.
