Not a JW here BUT at 150 is he and she not in a rather Professional Career environment? I so thought that this was NOT the Jehovah Witness way. The preach one thing then put something else in their video how confusing is this?
Being a nurse is okay, because that only takes 2 years of college. Becoming doctor is what would cause everyone to question her spirituality. Of course once she's actually a doctor, suddenly the WT would ask her if she'd like to donate her time to treat Bethelites for free.
