A person who is ‘diffident’ is reserved and unassertive. The word stresses a distrust in one’s own competence or ability which leads to hesitance and a fear of speaking up. Such a character trait can be very limiting in a professional environment, and also in a social one, where it may cause others to mistake your reserve for rudeness.
