It does not define my happiness (my children do that), but I like nice things.
I like driving a nice car, I like having all of the latest gadgets and gizmos, I like going on nice holidays.
When I was in the UK I simply was not able to do all of those things all of the time.
Part of this was because I was first setting up my business and chucking a lot of my disposable income into that, but also because the UK in comparison to where I live now is a rip off.
I had a good income in the UK, but my living expenses over here are absolutely peanuts, and with these peanuts I can live far better than I ever did in the UK. It isnt my business (although pretty successful) that has allowed me to have nice things now, its my access to disposable income because the cost of living is so cheap.
Moving to SEA isnt a solution for 99.99% of people, I get that, but my point is that money (and by that I mean disposable income) does make a massive difference to how you live. In India I work to live, and I live well. In the UK it felt as if I was living to work.
This thought process was a major catalyst on why we decided to move continents.
