American fashion designer Marc Ecko is using a song by The Notorious B.I.G. to help teach a business class. The clothing entrepreneur is set to launch the Run Your Own Business: Lessons from Biggie (Smalls) Skillshare online course and will use the rapper's classic single Ten Crack Commandments as the basis for the class. He says, "One of the most important lessons I have learned through two decades of building my own businesses is that wisdom and guidance can be found in the most unlikely of places. As a result, I've structured this Skillshare class on my principles of business around the legendary hip-hop track Ten Crack Commandments by Biggie Smalls. "On the surface it would appear that Biggie is rapping about illegal drug sales, but the knowledge dropped in this song actually applies to all businesses, no matter the industry." The course will cover business fundamentals like management skills, enabling ideas, and refining the business owner's personal brand, and Ecko is also offering a $5,000 (GBP3,330) endowment to a student who creates an inspirational business commandment from a song lyric or pop culture saying, according to AllHipHop.com.
