September officially marks the beginning of the Back-to-School season in the U.S. and many parts of the world. Images on TV show students all over the world boarding school buses, purchasing school supplies and assembling on college campus quads.

But I see another Back-to School scenario, and it looks quite different: adults, at home engaged in the best courses the world has to offer with just a computer and a willingness to learn. Back-to-school should really be for everyone; adults and kids alike.
