This has probably been asked a million times before, possibly many of those here on HEXUS, but I got the inspiration to ask too...
Would money change you? Not just a tenner or something obviously, but millions of pounds.
Personally I believe that whilst I'd treat myself (and possibly my family) to a couple of things, as a rule I would act the same as I do now, particularly on the subject of spending, since I'd like to think that I value the worth and would make little to no changes to my life.
If I were to win the millions via the lottery (the real ones of course, not the emails trying to con you), I'd choose the No Publicity option, and keep it a secret from most people (I'd probably tell my closest family and most trusted friends though, but that's it) - hence why I say I wouldn't act any differently.
