complicated

It's been almost 4 months since I started working.. I couldn't say anything against the company I'm with because all of the people are treating us nice.. We work in a good environment with professional leaders who would always provide us even the slightest need we have. However, I still don't fill the fullfilment I'm looking for. I don't enjoy the job itself.. Maybe because I didn't want to be in this in the first place.. Now, I'm struggling everyday just to deal with the confusion that I have.. Whether to resign, study again and do what I really want to do, teach.. Or to continue working for a good company who's promising me a good future but not the kind of job I would really want to pursue.. Sounds simple but at this point, its really complicated..
