I really like this video by Teal Swan. It is about a kind of self work that involves bringing a higher vibration of a optimal “future self” into the present with you, and then that higher vibration can integrate into your present self.
The only thing I would say about this idea,in addition to what Teal says if that you need to be able to self hypnotize for this to work.
If you are interested in learning self hypnosis, or you want to experience being hypnotized for self help work, you can contact me through my web site gentlekindnesscoaching.com
I can do a guided meditation with you and I can also teach you how to do a guided meditation with yourself.
