Translation of caprice in German

Probably we will make additions to our dictionary. I'll be available in January and in February, but not in March, because I'll be in the United States for about three months. About a week in New York, a week in Chicago and Detroit.
I usually do not travel, and if I do, then only to England, when I visit my parents who live in a suburb of London. I can not afford to travel too much, because it is a very large expense.
I've chosen a subject but for now I take a lot of art and language courses. Thank you for your tips! They helped me a lot. My uncle is a music teacher, but my father studied economics.
