If you think of your students as just an obstacle that stands between you and 3 o'clock or the weekend, they can probably tell.
If you like your students or don't like them, they can probably tell.
I am not saying that your goal should be to love (or even like) all of your students, but you can definitely care about all of them. There are little things that you can do to show this.
Going to extracurricular events like sports games, musical performances, plays, etc. shows support for both your students and your school. You would be surprised how much this can mean to your students.
Don't just be the type of teacher that punches the clock every day and tolerates students as a necessary evil on the road to getting a paycheck. Show them that you care. Support them in any way you can.
