What kind of job do I want in the future?

So I know what I want to become, I want to become a nurse. My mom told me that when I was little I also wanted to become a nurse. Yes, I want to help people who are ill or need help. I want to support people who have to be in the hospital. Maybe I decide to work on the children-department. I know I have to learn more then, but supporting children in a hard time seems good. I love children. And helping them in a hard and sad time would make me feel in a good place. I want to help people, and maybe save lives. I almost never had to be in hospital and if I were there I would go to the dentist-department or I would go for an open day where they show how it is in hospital. Or it was for someone else in the family. I went once for myself (as far I can remember) because I hurt my arm or something like that. But I hope I will be able to become nurse. Helping people is good, right? It would give me a great feeling, helping people is important, selfless and right to do.
