The document discusses problems with productivity like too many tasks, poor time management, and feeling overwhelmed. It introduces the Getting Things Done (GTD) method created by David Allen as a solution. GTD involves capturing all tasks, organizing them by project and context, and then reviewing and executing tasks to achieve stress-free productivity. Key aspects of GTD include having an inbox to record all tasks, separating tasks into projects, assigning contexts like location and time, and setting next actions to focus on the most important work.
