Why can't I be doctor?
Whenever I tried to be one, it only give me book is that normal?
Be rich, have several daughters, may or may not educated them early (if you play as female).
The good time is when they are at 7,8 they start study at the hospital (I don't remember much here, correct me if it's wrong, do some tests later year) or maybe 12? there's an announcement that they got scholarship from imperial place to be a doctor, you can play as them at this age. Or if one book is missing do another way:
When they turned to 17,18 with no job title, you can play a new life as the daughter, they possibly follow the doctor career (the panel of clinics to apply will appear in job)
Be warning: if you follow doctor career (only female) you will need to find a husband yourself at older age, harder to last your family tree. You can play as parent, set the daughter a husband, go to heaven, then play as her so that you cna both access to this job and (a handsome) husband =))) why girl can only peak their future man lol
