Oh yeah, I still kept my part-time job working for the city as a lifeguard, had a full time job at the airport fixed base operation, worked another part time job driving army trucks from AM General to railroad spurs around the area and loading them for shipment, and going to college full time, while dating my future wife, and even after we got married. Two weeks after she graduated high school she was attending business school in an accelerated Associate degree program in accounting. She got done in 18 months and got a job at a local financial institution where she's been employed for 40 years. 4 years later, we were in the black when we said "I do." We planned our budget on two people making minimum wage. Anything after that was gravy. And man, did we have a nice bowl of gravy. We've paid our first house off in less than 5 years. Paid off 20 acres in another 4 years. Paid off the next house in 3 years (would have been 5 but my father passed away so we used the money he left us to buy a used van and pay off the house 2 years early, thanks dad!). Had two kids. Put them both through Purdue debt free with a combination of 529 savings, cash, and they got scholarships.
We have stressed this story to our kids on multiple occasions:
Live well below your means!
They both get it, and started their ROTH IRAs as soon as they were able. Oldest owes less than $10K on student loans from master's degree. Has a very good positive net worth for a 28 year old. Youngest is in the black as well.
I realize we are more fortunate than many. We haven't had a catastrophic health issue and we've had steady employment. Despite loosing my job 4 years ago to outsourcing and taking about a 40% pay cut, we didn't even feel it. I was re-employed within 2 hours of getting my 6 week notice that I was losing my job. I was kinda worried about being marketable at 56, but it appears I'm in high demand because I have a pulse and can pass a drug test.

That, and a pretty good resume.
Anyhow, kids learn from their parents. I saw my parents struggle financially a couple times, yet still made a great home for their kids. I saw them worry, but never saw them fight. Great teamwork. Our kids never met my parents as they passed away before the opportunity. However, my in-laws are also great examples of a couple using teamwork to get what they want and my kids saw that for many years, until last December when my FIL passed away at 93.
We think it's rubbed off on them and we don't have to worry about them, although we still do. It's natural, I guess.
