Heya, my name is Sara, I'm a french/lebanese college student, and basically try to live by the following quote:
“Nothing happens until something moves.” -Albert Einstein. If you think that you're presence means nothing to the world, think again. If you are constantly moving, you are constantly changing the world, and therefore you are an important part of it.
Take chances, make mistakes, and live. It's only then that you will learn to understand yourself, and whatever makes you happy. Carpe Diem.
