Think of all the information that exists.
The top right quadrant is also good. You have information but don't need it right now.
The bottom left quadrant requires effort. You know what information you need to acquire.
The bottom right quadrant is unique. You don't have this information and don't need it. In fact, almost all the information that exists belongs to this quadrant!
Now think of a goal you have.
All that needs to happen is for the bottom left quadrant to be empty.
You already knew this. But now that you've seen it in a simple diagram you see how fundamentally simple the process actually is.
So go and achieve that thing you've been thinking of. What information do you need to get it done?
