Work or study

I already hold a master's degree from abroad and I am studying another one in Korea. I sometimes see some job opportunities that I could apply for with the degree I already own, but Im not sure I want to stay in that field my whole life, which is why im pursuing another degree. I sometimes wonder if id be best to drop out and apply to those Job opportunities but im scared id be stuck there if i find out its not right for me... any thoughts? (edited)
