2. Start a household budget book
Household budget books help you track your income and expenses, giving you a clear picture of where your money goes. Regularly reviewing your spending can reveal hidden, unnecessary costs—like that daily coffee-to-go—that add up over time. They also help you identify your savings potential and spot overpriced insurance payments or service providers, allowing you to make smarter financial decisions.

Talking About Personal Experiences
I first started a household budget book when I was around 18 years old. My parents gave me a monthly allowance of 50€, but somehow, my money kept disappearing—without anything to show for it. Frustrated and curious, I decided to track every cent I spent.
You can’t imagine my shock, dismay, and financial awakening after just one month!
At school, we had a coffee vending machine—each cup cost 50 cents. I had a routine: one cup during the morning break, another at lunch. That’s 1€ per day. Over 20 school days in a month? 20€ gone. On coffee!
I was spending 40% of my entire allowance on coffee—without even realizing it!
Thank goodness I learned this lesson before moving out for university and living on my own! From that moment on, my household budget book and I became inseparable best buddies - and still are more than 20 yrs later.
During my time at university, I had an average monthly income of around 1,000€. My rent was 650€, which, as you can imagine, didn’t exactly align with the "spend only 30% of your income on housing" rule. This left me with about 350€ for everything else. I allocated 100€ for food and set aside an emergency budget of 50€, which covered things like new clothes, shoes, detergent, toilet paper, and other essentials. Despite the tight budget, I managed to save 50€, with the remainder going toward service provider bills.
Quite frankly: this would have been an impossible undertaking without my best buddy.
My income during university came from a mix of a student loan, financial support from my parents, and earnings from part-time jobs. When I entered the adult working world, I had around 25,000€ in debt, including 5,000€ in credit card debt, with plans to pay it off over 12 years. Despite earning no more than 1,000€ per month, I managed to pay off the debt in just 8 years, with about 260€ going toward repayments each month.
