I can’t tell you how important this advice Neil Gaiman gives to this person is. I had a similar predicament but thankfully I’m an experimental type, so I came upon this one myself. Nothing revolutionary here but sound advice, nonetheless.
Mr. Gaiman: From a very young age, I’ve dreamed of being published (and hopefully successfully so). I went to college for writing and graduated. I couldn’t find a job in publishing, so now I work a different job full time and feel so mentally drained at the end of the day that tapping into my creative vein is often very difficult. Have you dealt with this before? If so, how did you overcome the exhaustion and just write?
Get up an hour earlier, and write for an hour before you go to work.
