To quit or not to quit, that is the question

I am sitting here thinking about the possibility of getting up at o-my god in the morning to go to another shift in Hell.  And so the question is posed.....to quit or not to quit.  If I get up at 5 am, be at work by six, work like a crazy person on meth who just left the donkey show, I will still have only earned $43 dollars after taxes.  If I show up and work really hard I just may get another $20 added on for the week.  If I don't move fast enough I won't.  This sucks.
Most of the time I would say, hell no don't quit, you don't have anything lined up yet...but then I stop and think, I am working ridiculously hard and still my cable is off, my phone is turned off, I have to get my car inspected, have two outstanding tickets on it, late on rent, and bill collectors keep calling, thinking somehow that I am going to pay them.  Get in line bitches!!!!  Take a number!!!!  The Check is in the mail!!!!
Considering all of this I just keep hearing the conversations in my head of "no one in the back ever lasts", "people can't handle all this hard work", and the like.  I almost feel like I am abandoning the troops or something, like I am letting down my fellow wage slaves by not being able to stick it out.  I feel like it is almost a challenge to take as much abuse as I can handle, like I can one up the next employee.  It is almost as if we are in some sort of unspoken contest to see who can be the last one standing.  I think we all take a little too much pride in the amount of bullshit we have to wade through each day.
On the other hand, $40 is $40 bucks, and when you are broke, you are broke and every penny counts.  Or does it?  We all pay a price for everything we do, I get that, but again I am left wondering if the exchange rate is just too high.
Meanwhile, I have had another couple of leads that I have grabbed ahold of, and so am hoping to hear from them soon.
Wish me luck, give me advice, or just buy me another drink.
