Pre-writing

I have found that this week frequently requires us to write things in advance. For example, this week we are writing three introductions for our research paper. We consistently have to write our papers in pieces from the conception of the idea to the very end which takes us a few weeks. While I understand the intention, I am very uncomfortable with it. 

I have a weird way of writing... whatever weird is. I will literally do all of it in one sitting. I snuggle up in bed with a glass of water, chocolate, and my headphones in. I spend a few hours doing nothing but compiling research, I do not even open a word document. Once I feel that I sufficiently understand a topic I doing the entire paper, no matter how long. I will sit for hours, usually in the middle of the night because that seems to be when I write best, and do nothing but write. Usually, I edit as I go so the finished copy is the final copy. And I turn it in from there.

So this class has been very weird for me. I have a very hard time breaking things into pieces. It stresses me out. I sit awake in the middle of the night thinking about something that isn't finished because dammit I want it done already. Also, I partially feel that I write better all in one go because my ideas are focused rather than, somehow, managing to scatter everywhere in a few days.

Does anyone else feel this way....?
