Julius Caesar is described as ambitious by his enemies. Whatever may be said of him, he wants to be well thought of by everyone. He is vain and perhaps self-centered. It. is not necessarily clear that he is indeed, ambitious. He does work hard, as he refuses to stay home from the Senate because of Calphurnia's dream (athough it is because a "friend" has interpreted the dream in a way to appeal to his vanity, making the horrible dream into one that honors him throughout all of Rome). He refuses the crown not once, but three times.
