I always knew that when you are a fresh grad, you will be cheap labor meant to be exploit. Well I quitted my first job after only two years and basically went jobless for 8 years. I survived by having very low expenses and doing biz with grants. It was a happy easy going life for eight years.
Downside , I missed the housing boom which my peers enjoyed and at 38, secured my second job which pays 8k a month. Of course I did that by fudging my resume and having an ability to think quickly on my feet irregardless of whether I have the experience or knowledge of the subject matter. It's not difficult , it is rare to meet a real pro in anyone's course of work.
Bottom line, I don't agree people should force fit themselves into any job they don't like. Quit and think of what you want to do. U can't if the job suck up your soul.
