Sit in a room with minutes to spare and task yourself this: to get to the market and back from your house. Maybe you shop for some fruits or something.
Step into your mental realm imagining every step you have to do in this task. Changing your clothes, tying your shoe lace, locking your door...everything. Not in frames but in a continuous motion as in a movie. It could be boring and I have felt the strong need to snap out of it. It still is difficult to power through, imagining every step and "looking" at the trees and shrubs along the way, picking up and inspecting an apple and putting it in the basket, paying for the goods, etc.
The whole thing is much more difficult than it sounds if you are the kind of person who gets restless easily. With practice, it gets better. Hopefully this helps you get in the productive zone. Good luck!
