Daily Review
Review Your System
To have your life under control you must review your system regularly, as often as necessary, so you can totally trust it.
Not everything should be reviewed at the same frequency. Two types of revisions are recommended: a more frequent one, which allows you to focus on what is important at the time, and another less frequent that allows you to keep your system updated and consistent with your goals in the medium to long term.
Daily Review
Depending on your activity level, you can do it daily, every two or three days or even more than once in a day. Ideally, either early in the day or at the end of the previous day, you need to be clear about what you have to do and what you can do this day:
Calendar
First you have to check your Calendar. Here you can find those actions you absolutely have to do this day. Take a look at the actions scheduled for the next few days. Maybe you can get on with some of those tasks.
Next Actions
Then check your Next Actions list. What actions and projects require more immediate attention? Update the priority / focus level.
Waiting For
Do not forget to take a look at your Waiting For list. Is there any delegated task that is getting stuck? Contact the responsible to track its progress.
Collect Every Thought
You already know you must collect every thing that comes to your mind.
If you have collected some stuff out of the GTD System (notebooks, notes, business cards, papers and the like) you can transfer those things to your GTD system at the end of the day. If the information is located in different places, you are not going to be able to make your decisions properly.
Do Clarify if Necessary
Then, if necessary, spend a few minutes processing the stuff you have collected.
