I was raised by a a child of the Great Depression and WW2, that contributed a lot. I still live in the house I built when I was 25 years old. While many of my contemporaries were selling and buying homes and constantly going bigger, I was paying double my payments against my mortgage. I was debt free at 37 years old. If we want a new car, boat , RV, vacation, or any other major expense, we don't borrow money. We save for those expenses ahead of time and pay cash at the time of purchase. Instead of blowing bonuses on a new boat we put that money in a separate fun money fund that I manage myself. That's our new car, new truck, new AC unit, new roof or whatever fund. If the money isn't there we don't buy it. We also both had small side gigs, nothing that we could live on solely but any money from those gigs went to the fun fund. It wasn't much each year but after 15-20 years it added up and it's multiplied many times over. Live below your means and save, save, save.
