Why do you want to become an astronaut?

I want to become an astronaut to explore the unknown, help others, and advance our society's understanding of ourselves and the world around us. I've always been a curious person, and have always wanted to push the boundaries of what I believe is possible. I would also love to serve as an inspiration to others, and to show that anything is possible when you have a dream.
