Look at this. The Daily Routines of Writers. Okay, almost all of them are writers.
I tend to wake up around 8 a.m., have my coffee and immediately start writing. I don't stop until about 1ish or 2ish or something, depending on the day, and until I produce at least 2K words (or more). Then I go eat, do social media, feed my pet crocodiles Cozy and Fuzzy , THEN I go read for at least 2 hours. Until life bugs me again to do dinner or whatever. Before bed I write a blog post, or read some more, and fall into bed, around midnight or so. Or even 2ish on some days.
What is your writing routine, if you have one?
