How to start writing

Through LBH and videos, I learned about how to write outline and draft. It is first step to write five paragraph. It is a draft so I don't have to write complete writing and it is OK to use "?" if I don't have enough information to write.   

When I write something, I tend to think about the thing only in my mind. So I have to write down the process of my thought. 

Also, When I write, I often go to library to concentrate writing because there is not noise.  However, sometimes speaking someone about the content is important, too.
