I don't think I'm fortunate at all. I think I made a decision about 20 years ago to save money and not give it to the banks in the form of interest.
Oh that and I worked my rear off.
It's very easy to do, just have to get used to delaying purchases until you have the money.
Personally, I would never have a car payment. But if I did, I most likely would not take an expensive vacation. I would make our vacation be a trip to grandma's house at the beach, a cheap tent camping trip, etc. I would use the money I saved to pay down the car loan. But that's just me.
If you have never been debt free as an adult you should try it. It's the most awesome feeling in the world and the freedom it gives you is unbelievable. The freedom to take awesome vacations, pay cash for big ticket items, send your kids to college and save money for retirement.
I am 45 years young and I plan on being a millionaire when I retire. It's actually very easy to do. Don't believe me, listen to Dave Ramsey (he's on the web and you can listen to his archived shows for free). I started making wise decision 20 years ago and only recently started listening to him. Finally, someone else that thinks like I do!
We don't have huge 6 figure incomes, we live in a fairly simple 3 bedroom house, my DH's truck is 10 years old, mine is 8 years old. We just bought our DD a new car last year that is fully paid for and we are cash flowing $17,000 per year for her college (yep, no student loans!). Last weekend we bought a brand new travel trailer that we are paying cash for. Instead of paying interest to banks we delayed our purchases. We use the money we save on interest to pay cash for our next big purchase. We always live below our means and we take awesome vacations...cruises, carribean, wdw, dl. And to think it all started because I decided I didn't want to have car payments!
