Fear.

(via)
Sometimes parts of life are scary. Really scary. But as long as I'm moving, I try to remind myself of what's scarier --- not moving at all. Not growing. Not learning. Not changing. Not caring. Not feeling. Not loving.
Because even though sometimes those things hurt and can be really scary, what kind of life would we have without them?
I'm learning that it's ok to have a not-so-brave face sometimes. I'm human. I'm imperfect. And sometimes --- I'm fearful.
