When I was in High School and College, I worked fast food and retail like a lot of young people do, and I learned the hard way that it isn't worth it to miss Thanksgiving dinner with your family, or getting home late on Christmas Eve because you have to work.
By the time I was about 21, I figured that all out and I used to quit right before Halloween. I would do most of my Christmas shopping in September and save as much money as I could all year, then would go get another job mid-January.
Before then, management would always have Holidays off and me and a few other young people would have to work and try to get out at a decent hour, but all the people off for that Holiday would come in to eat or shop and stay late that day and ruin it for us.
That was back in the 90's when jobs were easy to come by and my meager wage was enough to get me by, though, so you may need to think about it. I lived at home most of my College years, too.
It was hard being low on cash, and I would still take odd jobs and stuff, but I never regretted not missing important familiy time. Now that my parents and brother are gone, I'm really glad I did what was best for me instad of my employer.
