I am telling you this from my experience. When I started tapping few years back I was clueless how to do it on my own. Today, I can say I mastered it.
So what I meant by that?
When I first started I tapped by looking at YouTube videos of Robert doing Faster EFT. I tapped along, and I got some relief. Not a lot I must say.
I was overloaded by pain. So I knew it will take me some time to fix me. Today I come across some garbage stuff, that happened to me the same day. Somebody was mean to me, or somebody hurt me, etc…..I can then decide if I want to let go of this memory for ever. And I usually do it. I tapped, the whole protocol, plus few extra things that I figured out on my own, and it is gone, poof. The calmness settles in my mind.
So from my experience you become invulnerable. When you master Faster EFT, nothing is going to break you down anymore. You have the tool to clean all the pain from your mind so you will not become overloaded.
That is the beauty of mastering faster eft.
