FWIW I think that a lot of people make themselves fit what they are being told.....ever read your horoscope and MAKE yourself fit into the prediction??? Your sister reluctantly stood up when asked who's sister was moving abroad. What would have happened if she didn't stand up??? I bet someone else would have stood up. It the same when they say things like "the name Jon is coming through" Who doesn't know a Jon? or any other name for that matter. I think that if you make the move and hang onto this knowledge too dearly it will make you fail. Stick your fingers up to this and make your own destiny. Lifes full of ups and downs and I don't think for a minute your move will be "mistake" free which is the same for the rest of us.
Its your life do what YOU want to do. ;)
