I think being a teacher could be from home, however, I like the idea of being able to go on "school trips" (or university trips in this case), meet the students and talk to them face to face. I don't think I would like to travel a lot for my job, I would like to travel to nearby places with my students, but not out of town trips or very long trips, as these tend to be very tiring and increase the responsability one has to have.
I think that the salary is the least important thing, at least in my case, I have a secured house where I don't have to pay to maintain it, I only have to pay the monthly expenses of water, electricity and internet. I would like to have enough money to be able to eat well, I don't need millions, just good food and nice clothes.
At the moment I am finishing my last courses in history and theory, but I would like to do a major in history and theory as well, I think that with the courses I am doing it is not enough to be a good teacher for my future students.
