Assuming that you are comfortable-ish. I know there are plenty of people who dont have anything. This is for people who are fortunate enough to have some.
By "mad money" I mean "pocket money" or "selfish money" ie money that is set aside for you to blow on whatever you like and doesn't have to be accounted for.
And what do you spend it on?
I get £400 a month. It's meant for haurcits, clothes, nights out etc but I currently fritter it away on crap and then have no money to buy things I need (I need new trainers but spent it all so am currently wearing trainers that are worn and give me blisters).
Sadly I also ran up £3000 on my credit card (mostly non-essentials) so most of my £400 going forward will have to go towards paying that off next year. So I'll still be (relatively) broke!
