Final Step:
Imagine that your mind is a DVD recorder / player and you can review this content anytime you want. I want you to close your eyes and quickly review in your mind everything we covered in class.
I also want you to review everything we covered before you go to bed because I want your mind to process this information while you sleep. You don’t need to spend much time on this review, 5 minutes will be enough!
