I agree with those that say to make sure you have something else lined up before you decide to quit. Do it the right way, give notice, and let them know why you are leaving in a calm, professional manner. Don't do the "F**K it I'm outta here." Not knowing what you do, your absence may leave the company, and those you work with(and probably like) in a pinch. You never know what comes around a few years down the road when they're hiring for a job that you're interested in doing, and former co-workers make good references. What I'm saying is "stay classy."
