I've been working at my job for several years and I'm very comfortable here. Not sure if that is a negative or positive thing.

Thats a nice feeling to have job security. Do you enjoy your work?

Not especially. Also, I feel bad for getting so comfortable here because this is really not where I want to spend most of my career.

Well sometimes you have to leave comfort behind and take a chance doing something you like.
