My 2nd job while in High School was pumping gas at a Chevron station for $1.75/hr. The boss sent me to a week long class to learn how to upsell things like fan belts, tires, oil changes, etc... After attending that class, I got a raise to $2/hr plus a 10% commission on whatever I sold. That was in 1971, things were cheaper then but wages were lower as well.
I've never been into fashion, brand names or expensive clothes and fashion accessories. I bought used cars and drove them for years until they fell apart while I watched friends buy or lease new cars every few years. I did my own oil changes and other maintenance and repairs. I did my own yardwork, upkeep and remodeling projects on my house. We had 4 kids so paying for daycare would have been killer so my wife and I worked different shifts (I worked 1st shift, she worked 2nd) so that one of us was always home with the kids.
When I attended college, I worked full time days and went to school at night. I paid for all my books and tuition at the start of each semester so never had any student loans to pay off after graduation.
We had one extravagance, we owned a 30 ft travel trailer. Have you ever heard the saying that a boat is just a hole in the water that you throw money in to? Well an RV is just a hole in the ground that you throw money in to. We took trips with that RV at least 1 weekend per month, all year round. We camped in the woods, the beach, the desert, RV campgrounds, etc...
