Oh, that's too much of a general question and really, EFT can be applied on anything. There are so many blueprints and methods out there, but ultimately create your own. That's my greatest advice :)

And by the way, if you're interested to know, I'm beginning to study psychosynthesis, a really cool holistic approach to psychology, a psychology for the soul, created by Assagioli, an Italian guy who was a contemporary of Jung and Freud. Check it out, it's such a superb mix of psychoanalys, spirituality, personal development, self-reflective practice, study of the soul journey.. :) I'll be making a post about it very soon.
