Bbl,
Yes of course all of us went through periods suffering when we first started, but majority of us were in our twenties with no family obligations, pretty much could afford to hit the reset buttom numerous more times if it fell through.
Having said that, we are here to give you advise cause you asked for it. We gave you our views and if you don't like what we tell you then why bother asking. I'm just trying to put you out of your misery but hey, it ain't my life at stake. Just don't say we didn't warn you if it never works out the way you dreamed of. I just hope your wife and daughter are as determined as you are in your quest, if you are planning to do this alone in Canada and then in Adelaide then you are probably not gonna see them much for the next 3-4 years, best of luck.
