If people knew and made a list of all the essentials, they'll be fascinating. One example, last year in October I need to spend 600€ in my car, and I didn't felt the weight in my bank account, I knew that I didn't buy a nice car for 600€. And also, I've made a line in my finances, I was in danger if I had 1000€ in my bank account, so I make sure I never go down than 1000 and only buy stuff I really really need when I have money two buy two times. Now I started a conversion of my campervan and I really want to live off grid, only a few spends like electricity (where I'll spend more but that's cool).
