First, this article made more sense for me once I switched the morning and evening sections. Morning is my time for organized, purposeful, uncreative progress on well-defined goals; evening is my time for uncovering new ideas hiding in the dark recesses. (Afternoon, by contrast, is my time for naps and mindless web surfing, or for getting nothing done if at my day job.)

For me, when it's time to start, the key is a combination of a low bar for success (it's okay to write crap; it's okay to write only a couple of sentences) with rigid inflexibility about achieving success (writing must occur EVERY NIGHT before I leave the writing room). There are other rituals, like the making of tea and the arranging of the desklight and overhead lamp, but ultimately it's the physical commitment to sitting in front of my computer or notepad for as long as it takes.
