I'm having some teacher senioritis. It's April, the end is in sight, I know I'm not teaching next year (though I'm sure I'll be back to teaching at some point) and.... I have no motivation to go to work. My students' behavior is crazy, I'm constantly drained, it doesn't feel like I'm able to teach them anything effectively, and I just want the year to be over. How do you keep up your motivation during the end of the year?
