As a freshman, I wrote personal comments on my resume, but I am introverted. I have studied fine arts on how to patiently write my resume and highlight my works.
It still depends on you. It is best to have hobbies, be patient, and then have confidence in yourself. Cheer up, think about your own advantages, face your own shortcomings and write it frankly. Introversion is not a bad thing, dare to face yourself and give yourself an evaluation, and seek truth from facts without rhetoric.
