Routines in a writer?
What are some routines a writer carries, timing of writing, when do you see your friends… please explain these. I need to write an essay on the routines of a writer.

A writer writes when the words comes to him/her. Which is usually the middle of the night.
It depends on what kind of writer you are talking about when you ask when we see our friends… Some writers write as a job and have specific hours (blah) others write whenever, go out and do things, have a totally free and random schedule… and then some are complete loners. I like to write WITH my friends, personally. They are like immediate feedback.

Sometimes when I have writer’s block I need to have a specific time to sit down and write, or I will completely ignore it, but mostly all writers have a time that works for them, or they just write whenever.
