I was intrigued by this technique when I learned it (and I'm a fan of Neville Goddard, but hadn't read this particular technique). I haven't tried it yet, because I've been trying to work out how to count very LARGE quantities of money. The kind of quantities of money that is really too large to count, and which exist only as numbers in a bank account, as an idea or concept.
I am, however, inspired by this thread to try this technique for a countable amount of money. One of my mottos (which I say whenever anyone in my family finds money from an unexpected source) is "Yay for free money!"
BTW, if anyone has any ideas on how to use this technique for large amounts of money (uncountable amounts), I'd be very pleased to hear it. I haven't thought of anything workable yet.
