If you are a boy, extroversion is good, and introversion is not wrong. A long talk shows that you are good at analyzing things and like to make a sentence clear and thorough.
If your communication skills are average or not very good, then you can apply your calm characteristics to your study and engage in research or technical work in the future. Students' friends, if they have deep contacts and have reached the spiritual level, will be friends for life, and they will not care whether your personality is extroverted or not. However, if you just play together, they are just fair-weather friends, and when you go to school or find a job, they will die of old age.
Theoretically, personality is not easy to change, unless you have experienced any particularly significant stimulation.
You can think about it from another angle. Those extroverts are relatively restless, and they will feel insecure in job hunting and dating in the future, but your calmness has become an advantage.
Never envy others stubbornly, and find your own beauty is the source of happiness. When you find that your unique personality has brought you unusual gains, you will thank your parents, because they have long forgotten you in the westward journey.
