It's not just the small stuff, it's the big stuff too. Sometimes I buy really expensive things without really thinking about the consequences. Take last month, for example - I decided to book a holiday and buy a new laptop, with the promise to myself that I'd pop the money back into my savings ASAP. I know full well that this sort of strategy is going to lead to future months of fiscal anxiety whilst I try to replenish my savings, anxiety which could have been avoided if I'd just saved separately for the laptop and the holiday in the first place. And here lies the crux of the problem - when I want something, I buy it.
I wouldn't say I'm in financial dire straits, and neither am I really awful with money. I earn an average salary, of which I put around 16% each month into the eventual house-buying/adventure/rainy day pot. Every week we try to plan our food, meaning that it's rare that we spend over £40 a week between us. I have a decent job, no kids, no car and no real responsibilities. My money is entirely my own and my life is for living.
However, I think it's about time I had a long, hard look at where the disposable cash goes. I can't help thinking that if I cut down on some of the little bits, I'd be able to buy myself a few really nice things - that I actually need - every couple of months and not feel too guilty as a consequence.
With over half of the world's population being forced to live on less than a dollar a day, I want to put my spending into perspective. And that's where this challenge comes in.
