Have you ever gotten Blogger's Block? Every day for years, Trollope reported in his “Autobiography,” he woke in darkness and wrote from 5:30 a.m. to 8:30 a.m., with his watch in front of him. That's a strategy. He required of himself two hundred and fifty words every quarter of an hour. How about, say, 5 posts per quarter hour? (3 minutes each?)
