Good for you and you managed to say that without even blushing ! :-) And as for your spending, fuck it, why not, you're a long time dead and you cant take it with you and spending like that is all relative and is the same as someone earning a lot less spending 4000 on a night out, which of course they wouldn't think twice about, so my view, fuck it, spend it and enjoy while you can ( without leaving yourself broke at the end of it of course but at 1000000 a month salary I'm guessing you should be ok for a while yet :-)
PS if you ever need an ageing irish money boy ( who goes for free :-) you know where to call .......but just know I dont kiss, fuck, suck, or cum and dont do over nights .......ah hell, who am I kidding I do ALL of those things and hell for a lot less that 40,000 ( or even 4000) baht for that matter - usually more like two vodka and cokes and a kebab on the way home together ! lol
