When I was married to a JW, he was psycotically tight-fisted. So along with the JW thing, there was plenty of reason for never going out for a meal or a drink, always buying second hand (or not at all), and various weird behaviours all in the pursuit of "saving money". The house was always freezing cold because he refused to put the heating on.
So, when I broke free, getting to spend how much, when, and on what I wanted was wonderful, and I went completely over the top. I ended up badly in debt. I have sorted out my situation now. I still like to buy nice stuff, and when I have the money in the bank, I treat myself.
I have come to the conclusion that the thrill of buying something nice is about the same, and lasts about the same time irregardless of how much you spend. So spending 1000 won't make you 10 times happier than spending 100, and the fun happy feeling won't last 10 times longer. So, you may as well enjoy small treats. And be happy you don't have to work 16 hours a day to be able to have enough to eat.
