For the first-time novelist you've got to get up at 5:30 in the morning and write until 7, make breakfast and go to work. Or, come home and work for an hour. Everybody has an hour in their day somewhere.
As a young boy, I read 'Cheaper by the Dozen' and immediately became neurotic about my use of time. It taxed me severely, but only for the next 50 years. But I think it also allowed me to discipline myself to sit in the chair and be a writer, where one of the most needed qualities is patience.
