GTD 101 provides an overview of the Getting Things Done (GTD) stress-free productivity system. It explains that GTD can help anyone who feels overwhelmed by transforming overwhelm and overload into stress-free productivity. The key principles of GTD are to capture anything that has your attention, define concrete next steps for tasks, and organize information and reminders in a streamlined system based on how and when you need access to them. Frequent reviews across different time horizons help alleviate feelings of being overwhelmed and instill confidence by keeping commitments on track.
