Virtually every single thing I stress about in my life is in one way or another related to money. It's not spending money I'm into - it's having it. I have way more money saved up than anyone else I know but I still want more. You can call it an addiction but it's what gives me the peace of mind. 1 million euros is the number I have in mind about how much I'd need to have money saved up untill I would consider it enough. I'm nowhere even close that amount so it's safe to assume that money is going to remain among the top priorities for the rest of my life.
