When students comment that you like your job, it really says that they see you as an individual that cares about their success, and they know that you are not faking your daily interaction with them. Integrity comes out in our voice, our appearence, and our willingness to help them transition to a new future in a career that you (their instructor ) have enjoyed working in yourself. These are the indicators of genuine quality which can't be falsified as if you were acting in a play. Ones path has to be heartfelt or it will show up and students can see that we are in it completely or not, based on our daily actions.
