Talking about 100% accuracy, I was talking to someone today who was reminiscing about a reading they had six years ago. they didn't remember much of it, just the awesomely accurate bits of it.
1) The reader insightfully realised that she was never really understood by the people around her, and sometimes felt lonely.
2) The reader amazingly knew that she'd had a lot to deal with in her life.
3) The reader incredibly predicted that she'd have another baby even though her children were all grown up and she didn't, but that was okay, because her daughter-in-law and son had a baby the following year so the reader must have picked up on that.
4) The reader had the insight to tell her that the job she was in wouldn't last, but told her that because of changes in her energy it was impossible to tell her when it would end, and the reader was right - five years later the business she was working in closed down.
Now. If you say numbers one and two to most people, they will be egocentric enough to think that they are special, and not realise that every single living human being has a lot to deal with and often feels lonely and misunderstood even in quite good relationships, even if it's just momentarily.
Number three? Most people are related to someone who might have or might have just had a baby - it's easy for a reader to say that your family predictions got mixed into a personal reading.
Four: In this day and age, only a minority of businesses last more than three and a half years, and of those, only a small minority of their employees will still be in the same jobs ten years later.
So yes, by making careful predictions, you can be 100% accurate, and if the client asks pointed questions evade them by saying that "the energies on that aren't clear yet".
I could stick out a sign saying 100% accurate if I wanted - I know how to do it - but I've got a bit of pride about me.
