For a person to establish a point of view and then maintain that idea, he or she would need to have given a great deal of thought to the subject and also to related topics. Clarity of purpose or intent requires time spent gaining knowledge and considering the matter, which would be at a premium, as would discussion with other people. The process may be painful if the person is not familiar with the idea that criticism can be positive or negative, whilst covering both good and bad points.
Socially, having an assertive personality will mean that one is able to state one's case succinctly and ensure that the concept one is proposing is readily understood. In the absence of aggression one will never force an issue, but consider reasoned argument at a later date.
