When looking at my discretionary spending, I noticed I'm spending 300 euros on restaurants, take away meals, lunches, coffee, beer and fast food, etc.
That should be brought back to 150 euros. I've created budgets for each category, and it looks as follows:
25 on games and apps
50 on going out with the boys
50 for taking the ol' lady to a restaurant
25 on my hobby (electronics)
I've started using HomeBudget, which can sync from your PC to your smartphone, so I can't put off accounting for the expenses.
Summary: cutting back discretionary spending from 300 to 150 euros.
