Bussines Made Simple by Donald Miller is the latest book I’ve listened to. It is mostly an advertisement for his website of the same name, but nevertheless, it is not a bad read (or listen in my case).
Donald Miller’s goal is to give a business worker, business manager, or business owner the applicable knowledge to be an effective leader in what organization they are working in.
So for the cost of a paperback, you can forego that undergraduate business degree.
