We tend to shrink from our creative power. I can be in the middle of a great writing binge, where I'm really in flow, and start thinking, "I need a cup of tea." It's all I can do to resist it, unless I am aware of what's happening. So I do these little negotiations with myself, kind of like what happens when I run and my body wants to stop. "Okay, if I can make it to that next turn, I'll rest." Then I get to the turn and do it again. "Okay, if I can make it to that tree..." etc., until I've forgotten about stopping and get to the end of the run.
It seems so easy on a run.
