The business of writing

     I'd like to ask my writer friends how much time they spend writing and how much time do they spend on what I call the "business of writing".  I long to get back to the unfinished short story or the possibility of a poem.  Instead I'm focused on promotion, sending out work to perhaps be published, e-mails, preparing for poetry readings, and spending too much time applying for elusive grants. 
    Of course, I'm aware that I shouldn't complain and I'm lucky anyone would read my work at all.  It's just that I'm overwhelmed.  How did they do it?  Those writers who put in a full day at some office and came home to write long into the night.  I can't shake off the day jobs of which I have two and I need some time to do nothing when ideas may appear.  And I don't even have a family.  So I'm impressed by those of you who manage.   Any hints?
   After my trip to California, I've become fascinated by earthquakes.  Here's the Chronicle's page that shows how many and when they occur.

   I have a poem 18 minor quakes that perhaps I've posted before but need to edit.  Did I mention editing on my list?
