Interestingly, I finally found some research in the area of time management, but it hardly is a fount of new ideas. Instead, it is an empirical study of whether or not time management provides any benefit to the user, in very broad terms.
While this may seem like a common-sense question, I imagine that the author, Brigitte Claessens, who did this research for her thesis, was forced to answer such a basic question because there was so little scholarship on the question to begin with.
While I hope to contact her to find out where the cutting edge of the research might be, I wonder why there isn’t at least an online forum to discuss the ideas at the heart of time management. If it does exist, please let me know!
