Everyday in every way, I'm getting a bit better

In the film by Emir Kusturica 'Do you remember Dolly Bell?' (1981), Dino, a teenager interested in hypnotism and self reassurance as way for the individual to get from life what he/she wants, uses the sentence ' Everyday in every way, I'm getting a bit better'.

Is the challenge of looking into new ways of knowing that is relevant to this work. I am looking into self-hypnosis, learning by practice so I can understand how it works.
The experience of the general relaxation previous to the beginning of the trance for hypnosis, on the process of learning how to hypnotize myself, has been very rewarding.
