Your friend or co worker is going to lose his shyt if he gets divorced and loses the house .The funniest part I've seen people that will pinch pennies for years. One friend that couldn't even go out to eat lunch without asking his wife cause they were saving for a house. No vacations. No leisurely activities. Then after all that once they got the house they had to start saving up for renovations and to furnish the house. That was about 7-8 years gone by of saving money just to say they own a house. fukk all that. That's 7-8 years of experiences.
EDIT: I just remembered the friend that was doing all of that ended up in the crazy house for a couple months. The therapist he was assigned told him he needs to relax and take a vacation as that all work no play mentality lead to him being too bottled up. It was so bad my job was afraid to fire him because they were worried he'd kill himself.
I don't own a house yet but have a stable car that's paid off. Take 3-4 major vacations a year. And have enough money in the stock market that if I pulled it out could easily lay down a deposit for a new house. To me life is meant to be lived.
Now the designer clothes and expensive cars is personally dumb to me but hey however people define their own joy is not up to me.
