I came across Personal MBA on an Artful Manager blog post.
"Business schools don’t have a monopoly on worldly wisdom. If you're serious about learning advanced business principles, the Personal MBA can help. The Personal MBA recommended reading list is the tangible result of hundreds of hours of reading and research, and features only the very best books the business press has to offer. So skip the fancy diploma and $150,000 loan - you can get a world-class business education simply by reading these books."
