how to make it work while it's still rough?

I have felt a little rough the last few days, so today is the first day in a while that I have worked on my novel. I am still trying to figure out where to draw the line as far as getting the plot line in order without going overboard with revising while the draft is still rough - while I am still trying to get the story line on the page. I don't really know what I am doing here. I don't know how much is just setting things straight and how much is being obsessive and perfectionistic. I am trying to just work on it in small doses so I don't get too carried away and see if that helps me some. I have done one dose so far today, and I am thinking I will do one more before the day is out. Tomorrow, I will be substitute teaching, so I won't get much chance to work on the novel. I will get the chance to knit some while I watch kids do their assignments. That will be fun. I have a hat I'm working on knitting as a present for a friend; I will get some good progress done on that. I don't know if it is just me, but I always feel that I am neglecting something, no matter how I choose to spend my time. I guess that is just me being too perfectionistic, though. I need to relax on that score - a whole lot!
