I have no intentions of ever working at McDonald's, nor will I be happy there. So I'm not going to work for minimum wage. "OH it's a paycheck!" Great, so I'll have JUST enough to pay for rent and food, and be forced to be stuck at that fucking job. Then when I lose it, I'll be back on the streets. That's no way to start a life. Especially, when you have no one and nothing to fall back on.
I hope for your sake that you get these jobs and FIND a way to conserve any kind of saving that you get from these jobs. Consider 1 dollars left after paying all those foods and rents, for example. You save 30/31 dollars a month. Multiply that by 12 you get 360 dollars a month. If you can save 2 dollars, you get 720 dollars a year. So figure out a job that you can do and figure out how to consume less while maintaining your health somehow.
