I normally don’t go in for “self help” or faddish systems, but I’ve been using David Allen’s “Getting Things Done” (GTD) system for a couple of years, and I’ve found it to be a highly effective tool not so much for “time management” as for improving my productivity and efficiency — in other words, for getting things done.
Given that college students have many projects to manage, especially for classes, I think that the GTD system would be a great help. In fact, a number of college students have already “hacked” GTD to simplify and adapt it to student needs. For instance, check out this post over at Study Hacks, by Cal Newport.
If you are a student interested in trying out the GTD system, see also the entry at Wikipedia, which is a great (and free) place to start. You might also want to check out this online flowchart of the GTD system, which is worth downloading and printing for your notebook.
