The short-term-memory part of your mind—the part that tends to hold all of the incomplete, undecided, and unorganized “stuff”—functions much like RAM on a personal computer. Your conscious mind, like the computer screen, is a focusing tool, not a storage place. You can think about only two or three things at once. But the incomplete items are still being stored in the short-term-memory space. And as with RAM, there’s limited capacity; there’s only so much “stuff” you can store in there and still have that part of your brain function at a high level. Most people walk around with their RAM bursting at the seams. They’re constantly distracted, their focus disturbed by their own internal mental overload.
Before you can achieve... you'll need to get in the habit of keeping nothing on your mind... not by managing time, managing information, or managing priorities. ...Instead, the key ...is managing your actions. ...[T]he real problem is a lack of clarity and definition about what a project really is, and what the associated next-action steps required are.
Most often, the reason something is "on your mind" is that you want it to be different than it currently is, and yet:
• you haven't clarified exactly what the intended outcomes is;
• you haven't decided what the very next physical action step is;
• and/or you haven't put reminders of the outcome and the action required in a system you trust.
That's why it's on your mind.
Thou comest to me with a sword, and with A spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied. [...] And all this assembly shall know that the Lord saveth not with the sword and spear: for the battle is the Lord's, and he will give you into our hands.
