Your a Dad's attitude towards your success so far says more about him than you. You want to please your Dad and get his validation, but he is pushing his view of what you should do without having the information you have about your career. He also has little at risk other than wanting to be identified with your success.
His view of your career is incomplete and it would not be wise to accept it. You know what is best for you because you are living it oevery day. Listen to what he says, but go with your own decisions.
