Here is a short paragraph from the GTD Times blog describing the approach:
“Sophisticated without being confining, the subtle effectiveness of GTD lies in its radically common sense notion that with a complete and current inventory of all your commitments, organized and reviewed in a systematic way, you can focus clearly, view your world from optimal angles and make trusted choices about what to do (and not do) at any moment. GTD embodies an easy, step-by-step and highly efficient method for achieving this relaxed, productive state.
Implementing GTD alleviates the feeling of overwhelm, instills confidence, and releases a flood of creative energy. It provides structure without constraint, managing details with maximum flexibility. The system rigorously adheres to the core principles of productivity, while allowing tremendous freedom in the ‘how.'”
