I mainly need to improve at dealing with the inattentive students. I feel like I need to really focus on this at the beginning of the year because once you lose them its much harder to get them back. I think if you can identify them within the first couple of weeks before they have fully checked out, there's a chance to bring them back by talking to them, giving them jobs, or noticing when they do work. Once they have moved into the part of the year where they've missed 90% of the assignments and have a 10% grade in the class, its much harder to pull them back, especially if you're holding to the no late work policy.
