If you had the opportunity to learn to run a business from someone who built a liquor store into a $60 million dollar business, would you take it? If your answer is no, or if you are immediately full of skepticism, you may just want to close this article. However, if that prospect makes you excited, here's a chance. Gary Vaynerchuk is the co-founder (with his brother AJ) of VaynerMedia, a multi-million dollar marketing agency and one of AdvertisingAge's 10 agencies to watch. Gary is also one of the earliest investors in Twitter, Tumblr, Uber and BirchBox. Needless to say, the guy is good at picking what's going to work.
