Being egotistical, narcissistic, or stubborn indicates that you believe your needs and views are more important than other peoples. I suggest finding way to channel your anger physically and constructively. This will leave you more receptive to mindsets like “Your viewpoints and needs are as important as mine” or “How can I help?” Or you could start to listen, understand, and acknowledge the other person’s position. Or you could work together to find solutions. Or you could consciously practice surrendering your own desires for what’s best for the other person.
