As I said I am pretty close to the whole sound engineering training sector and yes we know about it and we have got the books and the videos but no one uses it though. Ever wondered why that is.
Visualisation is a great technique but instead of trying to visualise a mix what you should be visualising is yourself achieving a fantastic mix and imagine the feeling of having done it too. Do this at night before you go to sleep. Feed that into your subconscious mind. Then in the real world you will just automatically do what is necessary to make it come to pass.
If you are having problems with a mix ask your subconscious mind just before sleep what the solutions are and it will give it to you. Maybe not immediately but eventually you will get the answers you need.
