Looking back through my last few days of drawings I noticed I end up with "lost" lines when I have no idea how I am suppose to translate a reference to the page. Those lines help me stay ahead of any fear from a blank page since no stroke is precious in that mess. This gives me the confidence to keep making marks until I figure things out. If I am lucky enough to feel I know what I am doing, I start on "searching" lines. Otherwise it a second pass from the "lost" line scribble with a better plan of action. I still have to search because I'm not skilled enough to make clean lines without some under drawing. "Clean" lines either come after lots of deliberation, hesitation and ghosting or are an over draw based on "searching" lines.
