You have no internet access in sub-Saharan Africa with a traditional laptop. 4G LTE USB dongles basically don't exist or they're as expensive as a cheap Android phone. WiFi and copper to the home isn't widespread in developing countries. Without the internet you have no ability to learn whatever you want or communicate with anyone. It's you that's living in a fantasy world. Why don't you try using a laptop without internet, or with intermittent internet access, for a month and then come back and see how productive you were?
