you can do it on just three hours a day

"... three hours a day is all that's needed to write successfully. Writing is turning time into language, and all good writers have an elaborate, fetishistic relationship to their working hours. Writers talking about time are like painters talking about unprimed canvas and pigments. (Nor is there anything philistine about writers talking money. Inside the ballroom at the PEN banquet, it's all freedom and dignity; outside, it's all advances.)"
