Well, there are a couple of ways you can be "blank." (more than a couple, of course!)
One way, I think the Billy Corrigan way, is to recognize the newness in each moment, to be fully present, free of prejudices about how the moment *should* be and open to and accepting of what is in front of you. Anything can happen in that moment -- you are free.
Another way is to be so busy making meaning about everything, like what christmas *should* be like, how people *should* be, how you *should* be or do or have or experience something or other. When Reality and Should collide, you just go "blank" -- but it's not the blankness of infinite possibility, it's the blankness of overwhelm, resignation, and apathy. "I have learned to live with this and it doesn't bother me as much." Another word for it is "shut down." The only thing there is more of the same -- no freedom.
The good news is: you get to choose in each new moment. Now, and now, and now. Even if you choose not to make a conscious choice, you are still making a choice.
