I often meet people who ask how to study a topic, what school should they go to, and I say aren’t you old enough to just go learn stuff by yourself? Most researchers are terrible at explaining why their projects offer the world the best progress bang for their effort buck, but I have no problem offering such explanations.

Learn at own your pace.
