The GTD System
GTD (Getting Things Done) is a stress-free productivity system. It allows you to plan tasks efficiently and execute them organically.
GTD is based on the idea of freeing one's brain from remembering current tasks. To do this, all incoming information is transferred to an external medium, to paper, to apps.
The goal of the GTD system: Gather all tasks into a logical, reliable system, not to keep tasks in your head, to write everything down
Train yourself to make decisions about what to do next
Set an effective reminder system
Managers of 40% of the Fortune 100 companies use the GTD system. Among them are Microsoft, Coca-Cola, Deloitte, and Harvard University.
