If you're living within your means, and not a burden on family or society, who's to judge how you spend your money?
Was your cousin smart with her money? Don't compare your lifestyle to others.
We eat well and buy good food. Our kids do sports. We have hobbies and multiple pets. We save a little for retirement. I like nice shoes.
We also rarely eat out, rarely drink, don't go to movies, don't take luxury vacations. We shop thrift, do our own home repairs, live in a tiny house with one bathroom for a family of 4, drive cars that are 10+ years old, have a small garden, hunt for some of our meat, clip coupons.
