If the students think your only here for the pay check they may think your cutting corners . If you show you really are interested in them as a person and a student you will get a lot more from them. Show you care, interact with them and go above and beyond what is expected; find the ansewer to their questions, help them with a problem that may not be your course, etc. and they will become more then students. If you're there just for the pay check it will show and they will look elsewhere for guidence and knowledge. Besides the day will go a lot faster if your not always looking at the clock to see if it's time to leave.
