I am OK off these days, but have never really considered myself rich, but I go months without checking my bank account or even credit card bill. I don't need to as I simply know that I am spending less than I earn. Even at university when I had £5000 too live on in London, I rarely checked. I come from a frugal family, so I always consider before I buy something. But even for larger purchases I just know what's in my savings roughly and go for it. It helps that while I've not been commanding very high wages, I have been employed consistently since I left university 14 years ago.
