Am I brave?

I was thinking about something the other day and this line came to mind; it made me think which caused me ask myself this question:  Am I brave?  I don't think I'm very brave. In fact, I think that when hard times come, or difficult situations arise, I try to smooth over the confrontation.

"Sometimes I wonder about my life. I lead a small life - well, valuable, but small - and sometimes I wonder, do I do it because I like it, or because I haven't been brave? So much of what I see reminds me of something I read in a book, when shouldn't it be the other way around? I don't really want an answer. I just want to send this cosmic question out into the void. So good night, dear void."

Are you brave?  What are some things that define your bravery?
