i would say go for it, you only get 1 shot at life.
money always seems to sway people away from taking the plunge i know it does with my Mrs, but the way i look at it is if i can do it here i can do it anywhere! work that is.
personally I'm starting to hate this country the harder you work the more you get taxed ,the less you do the more they throw at you!!!!
America would be my country of choice , have got family spread across half of it and Canada, the wife's even got the chance of a transfer to new york
need to lots more gentle persuasion !!
