My wand is a combination of Ash and Unicorn and has immense healing properties. I think I am destined to practice the healing magic devoted to improving the mental condition, especially since damage to the mind can be the most difficult and lengthy to cure.
I've always loved animals so I think I might like to work with magical creatures, although I don't think I'd like to work at the ministry in regulation, so maybe a magical creature healer? The wizarding version of a vet I suppose.
I'd like to be a scientist and research the mechanisms that allow magic and incantations to work (and create new ones), or maybe I'd research transfiguration. One more options is about parallel worlds, but those don't exist in HP universe (as far as I know).
I would like to work with werewolves after reading the Harry Potter series and thinking about the struggles Remus Lupin had at keeping a job and everything I would like their job to be easier. I mean a werewolf has life about as hard as AIDS people or other diseased people once had. Although I do understand that not every werewolf is good. Some of them are bad, but then there can be bad in any type of person.
I'd love to be a healer and find a way to heal those like Neville's parents and Lockhart. I'd love to be a therapist - I think one could really be used after the war. I'd love to work with animals. But in the end, I want to be a Hogwarts Librarian and invents all sorts of fun spells so books are returned on time and students don't talk in the library
Like February and Anisia, I think I'd like to be a Healer. Maybe in research or a psychiatry/psychology-based Healer? I think it would be cool to cure people like Dumbledore's sister Ariana. Then again, a spell inventor would be cool too...
I think I would rather start with one dream job, then eventually move on to a second before I retire.
I would like to be a Herbology teacher or if possible a "Herbology/Potions in Healing" teacher (something similar to a pshycopharmacology teacher in the muggle world). Focusing on plants and potions that are used to help aid mental illnesses such as anxiety and depression, etc.
Then eventually maybe become a healer in that field at St. Mongos.
In real life, I am going to school to work with children and youth who have mental illnesses or disabilities (or possibly youth criminal justice, not sure yet). I also enjoy being around children of any age and I have many plants and flowers that I care for at home, so these jobs would be a perfect fit.
