EFT - emotional freedom therapy - for selfesteem issues
EFT is my all time favorite. Free, easy, highly effective.
Though, behind a seemingly easy method, it's only long-time experience that helps to get the most of this effective technique. Sometimes it's just seemingly details that matter.
Free manual for EFT, all you need to start, can be downloaded from Emofree web.
If any question, don't hesitate to discuss in the board. I have a lot of personal experience with EFT.
