My sister has grown tired of nursing as well. She spends about 85% of her time doing CYA paper work to keep the hospital out of court. Very little time is spent actually attending to patients. She is roped into that work until her kids finish college.
At least my children know better. Both daughters are doing non-medical stuff and my son is working for a large multinational and finishing his PhD in electrical engineering. They learned from observation and without any push in either direction from me.
