I was thinking about quiting my job

Sometimes, I can't stand the situation I'm in. The fact that my job requires patience and everything makes me sick. My job is so jobless. Sitting for over an hour or more--totally makes me sick. Sleepy? Yea. It happens--everytime! Nothing is right. Lots of customers, trouble us. Gotta be in 2 or more places at a time. No customer, trouble us, too. Gotta make money for a living. I mean, yea. I need experience since this is my first job. But, it's not like how I imagined it. It's boring. But then, have to holding on. This is not for forever.
