If you lack social skills, or have weird hobbies, you will slap the “introvert” label on yourself to empower yourself. “I’m not a freak, I’m an introvert.” And putting such labels on yourself is exactly the problem. The label of a “cool, but lonely introvert” is nothing but a defense mechanism.
Of course being an introvert is OK. It’s a natural part of who YOU are, it comes with a lot of advantages and, yes, sometimes you’ll get tired if you’re around certain people too long. But introverts can be fun, interesting, social, and even outgoing when they want to be. Sometimes it takes getting comfortable with your surroundings. And this might take a while, it varies from person to person.
Marlin is an example of a dynamic character because he grows and changes throughout the movie. At the beginning, he is very overprotective and doesn't let Nemo do anything but towards the end of the movie he begins to let go and trust Nemo.
