It's tough when you're in school full time. No one really wants to hire you if you're only around for breaks. I worked at a chain drug store from my senior year of high school to my senior year of college. For the most part, it sucked. But they always gave me hours, so I sucked it up.
I tried babysitting, tutoring, and a few other random things, but retail really is a steady job.
I was a shift supervisor, so I lived for the days that I was the only one in charge. Then I'd sit in the office, read magazines, call my boyfriend, paint my nails, etc. But when the manager or other shift supervisors were there, it was quite miserable!
I had an eating disorder most of the years that I worked there. It was quite handy to have diet things and splurge foods at my disposal 30 hours a week. Not healthy at all, but handy at the time.
Bottom-line- it's tough to hold down a job when you have other issues filling your mind.
For me, I said, "I need the money. The day will come when I will actually like my job. For now, I will suck it up."
I don't know what it's like in your head, but I guess you just gotta decide if the torture is worth the money. Decide if you can live without a cash flow for a bit of time.
Good luck!
