Harry Dexter Kitson

How to Use Your Mind was written in 1916 for American undergraduates and is a study manual: how to read a textbook, how to take notes, how attention and habit work, all resting on the psychology available at the time. Kitson was a Columbia psychologist who worked on vocational guidance and on the psychology of advertising, and was among the first academics to treat the choosing of a career as something that could be studied at all. It is a period document, and the practical advice has aged considerably better than the theory underneath it.
