The theory is sound but it assumes that I am able to move to any country legally to live there. That requires certain types of passports which I was not born with. It also has more assumptions to what my financial/family situation is. I don't meant this in a negative way of course since you don't know me but what I am saying is that this plan is not always possible.

The idea of keeping expenses down and foregoing frivolous luxuries is what allows me to wait for a better offer inbetween jobs if i needed to. So I strongly agree with that bit.
