Having an opinion will help you talk to people and make your conversations more interesting. If you meet someone and they say something you don’t agree with, don’t be afraid to respectfully state your opinion. They probably will think you are more interesting than if you just agree over and over again. Write down specific traits you admire in others that you want to add to your personality.
For example, if you meet someone try to find out what makes them interesting. It doesn’t have to be a constant stream of questions but balance talking about your own experiences with what they say. Maybe you really like mountain biking and you notice they have a mountain bike. Don’t start talking about how good you are at mountain biking - ask them a lot about what they enjoy.
For example, try to find a way to make people feel comfortable and less tense if something bad happens. If your teacher moves your paper forward a week don’t moan and complain - make a joke!
