That's pretty much been my philosophy since starting work & done more than my fair share of Saturdays, but I never relied on overtime for expenses/living costs, it was mainly used for `extras`.
A good friend of my missus, who in reality could afford not to work, used to put as many hours as poss in @ work (inc overtime) and put
ALL her wages into savings so she & her hubby could retire in their early 50's. Although not `tight` with their money, they didn't really do much of anything.
She dropped down dead at 44 years old.
I've known a few folk who maybe didn't enjoy life as much as they could, saving for retirement etc & popped their clogs well before retirement age. It's no good saving for a very comfortable retirement if you don't have the health to enjoy it.
My missus had a serious health scare a few years ago & it does make you re evaluate what's actually important. Life is for living!
