When j. k. rowling was 21, what is the only thing that she thought she wanted to do in life?

J. K. Rowling has always wanted to write and be a successful writer, even though her parents didn't believe in her initially. They thought that writing couldn't support her in life and were thus against her wishes. They wanted her to study languages, which she did in the beginning (she enrolled in Modern Languages, however, later transferred to Classical Languages), but soon realized that her passion for writing never diminished, which is a good thing because we wouldn't have the Harry Potter series today otherwise.
