This drift seems to be more about morality than about what to do with your life. We all have to live with the consequences of our actions, whether or not we go to gaol for them. We are not the good shepherd, chasing after the missing lamb, we are the people doing the best we can with our own actions.

If Lavender sets up as a publican and enjoys keeping an eye out for her neighbors as well as having a good time for herself in between the labors needed to provide the publican's services, so be it. If she chooses a less demanding line of work, this, too, is her choice.

The original question was: Should I change jobs and how should I go about getting out of doing what I hate? Digressions about the morality of her choices are more for people to get their rocks off on the pulpit provided than to say anything useful.
