There is this, https://www.mrmoneymustache.com/2012/01/13/the-shockingly-si... which is pretty similar. And yes, I am well aware not everyone can achieve this. Families are expensive, eating out with friends is expensive, not everyone makes $X per year.

But still, some people live on as little as possible and invest in their retirement aggressively. I have some friends who are into this, they drive that same shitty car from college, live with roommates, cook everything at home, etc. They are content living with that knowing they are investing for retirement in their 40s.
