Be assertive not aggressive

It is a myth that successful managers are aggressive. They are not aggressive, rather they are assertive. There is a fine dividing line between assertiveness and aggressiveness. An assertive person is someone who puts forward his point hand, tries to dominate others. He raises his voice, he does not listen, and he does not seek to understand other people's points of view. He gets emotionally involved in his arguments. He takes it as a personal affront if others disagree with him. He ends up offending others. So do not be aggressive in your next GD. Instead, be assertive.
