I work best late at night and tend to work better in a cluster - i get on a roll i guess where it flows much easier. interruptions can kill a layout.
I rarely have a plan and even if I do it never ends up looking as i thought. It goes where it goes. Having said that I am pretty linear though I do try to move out of that.
The biggest influence on my creative process is color so I don't care where a element or paper comes from as long as it works.
