This can become a problem when building a relationship, going out in the career world or communicating with friends, family members, and co-workers. Assertiveness is the ability to express your feelings, opinions, beliefs, and needs directly, openly and honestly, while not violating the personal rights of others. Assertiveness does not in any way means being aggressive.
Aggressive behavior is self-enhancing at the expense of others.
It does not take other individual's rights into consideration. Develop your communication skills. Allow you to feel self-confident. Increase your self-esteem. Help you to gain the respect of others.
