Getting Things Done
Web app Toodledo has a useful summary of GTD here:
Getting Things Done (GTD) is a method for organizing tasks so that you can focus your entire energy and creativity on completing those tasks in a stress free manner. This method was developed by David Allen in his book, Getting Things Done. The main principle of GTD is that recording your tasks in a reliable way – using a system that you trust – will free your mind from trying to remember and prioritize stuff. This recaptured mental energy can be put towards being more productive and efficient.
