Did you know there is an “eBay University”? Neither did I. But there is. Mind you, it’s not Harvard, but then if you want to earn a living as an online trader, a Harvard degree won’t be much use. (Also, all the smart entrepreneurs seem to drop out of Harvard. Think of Bill Gates. Think of Mark Zuckerberg, the 22-year-old founder of FaceBook, now apparently worth $900.)
