How do I describe myself?

I'm a highschool student, currently studying in Pin Hwa High School. Most of my friends have stated that my first impression is that I love to smile to everyone, maybe I'm used to it. I really hope that I can bring lots of laughter around them.

However, I'm also an introvert. I am a person who likes to be alone in my world, but I also try to change myself, broaden my vision and try to care about people and things around me. I still have a lot of things that I need to learn, thus I hope I can continue to learn actively and keep an optimistic attitude in the process of learning so that I can become who I want to be.
