I'm taking a course of studies through a seminary. I have the option at any time of physically traveling to the seminary to finish the degree, or I can do most of the work by correspondence.
It's not an MBA or CA designation (I'm working on an MTS) and at best, I'll end up doing the lecture circuit or living under a tree preaching and living off mangoes in the underdeveloped world, but I find the courses to be extremely valuable in other fields.
For example, I had no idea half the adult population of Swaziland was HIV positive. I had no idea where Swaziland was, but now I am in a far better negotiating position when I deal with people who are Afrikaner and appreciate that I understand some of their history and also why they left South Africa for Canada. As a native born Canadian, I sometimes forget that not everybody has it as good as we do, and that not every product should be sold to the target market where it will profit most, if there are deliberate and definite human costs.
