I think being vulnerable in our culture is one of the most challenging things we can do. Generally we present some image to the world that doesn't represent our true selves- feeling, interests, etc.
Lately I've been trying to open up to people and life and let it in, let go of the fear that something bad might happen if I'm just myself. It's been really freeing, because I was one of those people who hid my emotions and feelings and opinions for most people.
