I really think people get hung up with "in the moment", spending. My house and car are also paid for, and I have nice clothes, one good handbag lasts for years, don't need 10 however, being retired and the cost of living, you feel you want to live, not always budget, so, I get it. I've cut way back on travel, drove a Mercedes when married, went from that to a great Honda Accord and never missed the other. now has 100,000 miles, just had an overhaul. My daughter rents a Mustang convertible when visiting, she won't drive mine as it doesn't have utube.
There are ways to cut costs, and i've learned them all, but rich is better....l think you'll never think you'll age.
I do wish I could travel more, as one ages, not only money, but friends are ill or gone... I was caught up in that life but we could afford things, my ex, always thought of the future more than me, still we were not flashy, very realistic...:nothing for show only, bought what we could afford.....
Live consciously....
