In retrospect, high school was easy. We had a roof over our heads and food on our plates. School was free and our books were given to us. We kind of think that's how it's supposed to be forever. Then, suddenly, we're thrown into college where we have to pay for all of that stuff. That typically means we have to get a job. Sure, there are those super-flexible jobs on campus, but they're usually only available through work-study, which you have to qualify for. What if you don't? No worries, there are plenty of options.
The most obvious route is to look into fast-food or retail. There's typically a good supply of employers in this category. See which ones offer perks like laid-back uniforms, free meals, or commissions. Just don't take a commission without an actual pay rate to go with it. That's basically setting yourself up to be broke, at least for a while.
Ask in person at a photography studio. It's the perfect gig for the artistic type and the hours can be incredibly flexible. Try working a night shift that's over by eight o'clock, leaving plenty of time for studying.
See who's looking for a bartender. It'll be a little harder to get the job and there will be more training involved. The hours will be later and busier than most other jobs too. If you're into the bar scene, though, it may be the funnest job out there. No, you probably won't be able to party at work, but you'll find that people's behaviors are more entertaining when you're sober, anyway.
Have you spent a couple years in school already? Look at the local school districts and see if they're taking applications for substitute teachers. If you meet the qualifications, you can group your classes so they fall on the same days and work the days that you're out of class. The daily rate is decent and it leaves your weekends and evenings free. It's a pretty good deal.
The best way to find a job that fits you is to roam around town. Pay attention to everything. Look at the stores, shops, and businesses scattered around. Pay attention to the signs hung from street poles. See what's offered and see what isn't. If you really open your eyes, you can find a job that's fun and allows you to eat hot meals more than twice a week.
