Starting investing into index fund ETFs

I only started about 3 years ago but even if I stopped putting in more money right now it would still keep paying me interests around 2000 to 3000€ each year for the rest of my life and it’s 100% passive income. In my case it’s all invested back into the funds though.

The second best move was starting to track my finances. It’s almost impossible to not change your spending habits once you actually see where all the money is going. Almost anyone can cut atleast 100€ a month from their grocery bills by just being a little more mindfull about what you buy. That’s 1200€/year or 12k€/10 years.
