Journaling

I've wrote about this in the past, but it bears repeating. First thing in the morning I like to kickstart my brain and my writing by doing some simple journaling. It is an easy way to get the blood flowing in the creative part of the brain since there should be no pressure on what you write or how you write it for that matter.
Journaling should be simple observations or thoughts that you may have. Possibly even write about what you plan on writing later in the day. That has two fold effect of helping you brainstorm for your main writing of the day and it gets you writing first thing.
Try journaling and see if it helps you. I know it is essential my writing routine everyday.
