Positive EFT is the easiest of all the methods that aim to change a person's emotional/stressful state. Most people will find it easy to try and use it because of its positive bent described below.
This approach of tapping on a positive that the client selects, to solve a problem like facing an interview, is very different from digging for events and reasons that resulted in the current problem.
The latter approach is very common in most methods, even very effective ones, and it is probably a carry over from psychology where digging the past laboriously is the norm and getting to a neutral state the final goal.
Interestingly, this approach of focusing on a positive to change state rather than starting and staying with a "problem" and its "related stories" is frowned upon in many EFT circles as well :).
I put it practical test with my a few of my clients and Positive EFT definitely lives up to its claims of effectiveness. It is very easy to introduce, clients find it easy to use and it results in good feeling states much more easily.
Given that it is still a new method, the jury is out on whether it can solve everything that the other methods can, but I won't be surprised if it leads to a new class of techniques in a few years.
What sets it apart from other methods is that you do not have to start with a serious issue or a trauma which is the default starting point in most other techniques.
You are asked to pick a positive state like joy, lightness, power, clarity etc. that you subjectively know will make you feel much better in the situation you are in.
Once you pick up a state, you use the Energy EFT tapping protocol as you pay attention to your personal meaning/feeling of the desired state.
After a few rounds of tapping, most people can easily notice an improvement in their internal state and improved feelings that corresponds to an increased energy flow.
This works pretty fast and most people like doing it as it has a positive focus rather than a trauma focus. So most people find this a great starting point to learn about relation between emotions and energy before you get into handling difficult troubling issues with something like EFT/Emotrance.
A long time client came over for a Emotrance session as he was pretty stressed and down over his work situation and issues with his boss at work over the last few days.
Instead of working through the events or his issues with his boss, I suggested we tried positive EFT. He agreed and picked 'radiance' as the positive that would make him feel good.
We tapped round after round personalizing it in his own words and at the end of the hour he was happy and buzzing, a sharp contrast from the stressed out state he was in when he came in. He has been using positives on his own since then and has not felt a need to visit me again for those issues again.
This highlighted the fact for me that just raising the energy levels using positives is often more than enough to get us out of disturbed states. Not always do we need to dig into the past to root cause and tap/emotrance on past events or issues.
