Patti Smith on her morning writing routine:

I get up and if I feel out of sorts I’ll do some exercises. I’ll feed my cat, then I go get my coffee, take a notebook, and write for a couple of hours. Then I just roam around. I try to take long walks and things like that, but I just kill time until something good is on TV…

Good ideas come when walking. Or watching shows, preferably ones with detectives. Thinking of better ways you could have solved the crime might be self-flattery but it also gets ideas percolating.
