When writing about yourself you have to decide what you believe: if you believe that actions define a person then you will write about you vocation or hobbies, if you believe that reactions define a person then you will write about political views, religion, or about how things make you feel.
I am an artistic person. I mostly draw, paint, and write. Creating anything makes me feel fulfilled and free.
I am an intellectual person. I mostly take classes, toss abstract concepts around my head, and read. This makes me feel capable and progressive.
I am an absorbent person. I mostly absorb sensual things like colors, sound patterns, and physical feelings. This makes me feel involved and purposefully alive.
I am a college student from North Carolina who loves to travel and have long, hair-splitting conversations.
