The only debt I ever had is my mortgage and I have savings to cover for at least 3 years without working. Without counting that I would get unemployment plus some other investments that would protect me more.
All this lifestyle didn’t stop me from traveling a lot (sometimes for months) and having nice things. But except for the home down payment, I never spent more in a year than I earned.
But I also admit that I missed a lot of good investment opportunities due to my risk aversion
