David Allen, the creator of GTD, says there is no standard way to use his method. Although his books and workshops provide a lot of explanations, it is important for everyone to create their own system that suits their needs and preferences. The goal of GTD is to get tasks and responsibilities out of your head, so you have space for creative and productive thinking. This works best when the system you use fits you well and feels easy.
Adapting your GTD system means trying out what works for you. This may mean setting reminders for things that interest you or developing habits that help you feel better. The most important thing is that GTD is not about strictly following rules, but about creating a system that helps you clear your mind. Whether you use an app or a paper notebook, it’s about finding a way that helps you stay organized and focused.
