Use the time you would work a second job and instead learn a highly employable skill. Specifically in tech/engineering, legal, or medical. There are certifications that can virtually guarantee people upwards of 60k a year which is a significant jump from minimum wage. You don’t need a ton of school.

I was in a similar position in 2019 - minimum wage, living with parents, late teens early 20s. I started studying network engineering at night from 8-10pm every night. 6 weeks into studying got an internship at a tech company. 6 months in I had amassed 3 more certifications in my time there and got onboarded as a full time salaried employee.

Make more now than I thought would be possible in decades.
