Dennis Psaroudakis learned about GTD nine years ago, and has been implementing it in earnest for the last few years. He uses GTD to manage a full-time job, as well as his work toward a PhD. He prefers paper for capture, but the rest of his system is digital. He chose Nirvana for tasks, and the Google Workspace for everything else. Dennis thinks that GTD is helpful even for people who are early in their careers and may not realize they need it yet. He says before GTD, "You don't know how much better your life could be."
