A blog effort of monumental proportions?

I always have something to say. This is true whenever I am talking with someone, or a group of people. I never run out of things to talk about, and always have an opinion to express. So why are putting words down on paper (keyboard?) so much more difficult? I know I have things to say, and plenty to talk about. Once I start a new post, inspiration always comes. My problem is clicking the button that takes me here. I guess sometimes I don't really feel like opening up and sharing, it takes too much effort. I don't know.
