I love You Need a.Budget, and when I started using it I realized how much I spent on food - specifically, "too tired to cook, too tired to prep, too tired to care" groceries and meals out. I'm an emotional shopper when it comes to food, too. I will spend more on food whenever I have an argument with my spouse it seems.
I also realized how much I was spending on various, automatic monthly subscriptions. It wasn't an enormous amount of money but I wasn't getting any enjoyment from most of them, so I just cancelled everything to see what I missed.
I do not spend much at all on entertainment, clothing and grooming, or travel.
I spend way too much on work supplies (I'm a teacher - I spend on my classroom. Need to stop that!)
