Visualization, if you have the underlying motivation, is how to get started. Then after 5 minutes of focus can be right into it..

At the moment I've gone through my morning websites, consumed everything I need to, replied to emails I need to, and now this is my second visit to HN ... so it times to make my work environment a clean slate, eliminate all distractions, and focus for a little while... perhaps I'm not awake enough for the focus required though either... |)
