Motivating your students is not always easy. There are days where the only motivation you can give them is a simple "thank you" for their showing up to class due to situations in their own life, though this is not an excuse for them to skip their work and study obligation to your class. What I have found, if the student cares, is that the best motivation to move them is their grade. They work, they get rewarded; they don't, they fail. It sounds cold, but it is the bottom line.
