What's Going On?!

Okay, I've been a little confused lately. I don't know if I was late the day we discussed what these posts are supposed to be about (haha, joke), but I really am lost. I believe that they are supposed to be helpful to us in some way, but what way are they supposed to be helpful? Are we supposed to know?
Mr. Watson keeps saying that we are supposed to be establishing our voice in our writing, but I don't know how to do that. You see, I consider myself pretty level-headed, and I like to know how to do something before I attempt actually doing it. But with this class, there is no check list or rubric, you're just supposed to keep writing until you "discover" your voice? It doesn't sit well with me.
Are we supposed to ask questions? Are we supposed to understand? Are we meant to be completely lost and not know what's going on until it finally clicks with us? I am sincerely in the dark! I would love to find my voice, but I first want to know how others have found their voice, or I want to know the steps to finding it. I don't like stabbing in the dark, looking for a specific idea that I don't know what it is. It's like trying to find a needle in a haystack.
If we are meant to find our voice through different outlets, are we supposed to write about different topics every time? Are the topics supposed to be open-ended question discussions, or just journals? How are these posts helping us discover our voices? I guess that is the underlying question: how does this help?
This is how I learn: I read, I practice, I study, I ask. That basically covers it all. So how does this particular exercise help me learn? Am I supposed to be doing a little of everything? How do these help me (personally) discover what my voice is? How will I know it's MY voice? How do I know it's not someone else's voice that I have totally just ripped off? Maybe a better question is, what is a voice and how do I know it's mine?
