Sofia, does this help?
This is the longer version of an experience I had. There is nothing 'expert' about it...just what happened to me.
Although I must admit that I am contemplating using this method to go after more important goals. To me, it is so easy. Forgetting about it, after making the statement, is an important step, I believe.
(A couple of other experiences tell me to 'let it go', not concentrate on the statement, after making it. Your sub-conscious already knows all the 'qualifications' you intend, I think.)
Here is how I wrote it in the Energy Healing forum (in case you are interested in more):
1985 I was having trouble reading the print in the telephone book (needed reading glasses, I guess), AND couldn't remember telephone numbers of new acquaintances.
Once more looking up Beth's number, I made a statement..."I will remember every number I need to remember, when I need to remember it." Then I went ahead and called Beth, with no further effort put into remembering.
Later that day, I repeated the statement...then forgot about it.
I think it was two days later...I put my hand over the receiver to call someone, and the number jumped into my head.
This capability has never left me, though, at times, I haven't used it for fairly long stretches.
I don't even have to think about it as a 'capability'. It's just one of the things I do.
My best,
fledgling
