I explain the rough overview of Getting Things Done for those who did not read the book yet. If you already read it, you can skip to the next section.
In GTD, after gathering what you care about, you process them. It is important that the phase of gathering and the phase of processing them are clearly separated. Instead of thinking while gathering, we first grasp the overall picture of how much we have. (*3)
In the phase of processing, for each thing you collect, ask the following questions:
If you think you need to take action, ask another question:
In other words, you need to clarify the goal. After that, ask another question:
In this way, you finally make the thing into a form of task.
After that, you classify the task according to concrete actions to be taken. I introduce them roughly.
By processing in this way, the actions you should do become clear. After seeing the whole picture of the action, you choose one task from them and execute it.

*3: Here I explain the ideal state to make the story simple. However, in reality, the time constraint effects. Allen says it is ideal to secure two days.
*4 Trying to do something too complicated from the beginning increases confusion with the overhead of thought. Simple is better than complex.
