If you have students, as I do, who come to you and ask how they can do better, point them to Study Hacks.
In this particular post, Cal Newport gives lots of hints that will help your students.

He also has some good tips for the academics. I have borrowed liberally from his Three Simple Rules for Making Your Free Time Count… I have free time. Don’t you?

And his new semester resolution is great too. Start by quitting something. You are probably doing too much. Stop.
