In conjunction with the release of his book "Unlabel: Selling You without Selling Out," Marc Ecko has created an online course via Skillshare that focuses on the principles of business. But it's not just any online class—it's structured around Notorious B.I.G.'s legendary song, "Ten Crack Commandments."

As Ecko explains in the description, the class is for anyone from "a young entrepreneur venturing into your first business endeavor to an experienced CEO running a company with thousands of employees." Ecko will be giving a $5000 endowment to the student who submits the most compelling commandment, too.

You can enroll in the class on Skillshare.com, but here's how to get in for free:
