This is so funny! You chose a thread title that to my sleepy mod eyes spelled -- Oh I had better check this one because it could run off the road in 8 directions! But then the video. :rofl!!:
There is a certain amount of value however in general. I would not pay all that money. Consider that in sports coaching athletes practice visualizing mental images of themselves performing a play -- for example, a tennis serve - perfectly and then applauding themselves. Not kidding -- this is for real and they rehe{censored} these images. There is some empirical research indicating that practicing positive imagery does result in improved sports performance under pressure. Personal affirmation -- as a therapeutic intervention -- is also used by therapists treating people with all kinds of addictions, people with insomnia, and people suffering from "shyness" that inhibits their ability to interact with other people in a normal way.
I don't have an opinion on this -- and only want to point these out.
