The document discusses stress and burnout experienced by project managers. It describes various productivity tools and methodologies tried in the past 25 years, including Lotus Notes, Outlook, SharePoint, Evernote, and OneNote. While these isolated important concepts from David Allen's Getting Things Done (GTD) methodology, the author realized he was missing a single to-do list. The author wants to share personal productivity best practices with others to help them experience less stress and more success.
