When I think back on my teachers who were most effective, there is something they all had in common: they all seemed excited to be teaching us. Teachers should always be aware of the attitude and energy they bring into class. I promise you, the students are aware of it.

When teachers show up for work, deliver quality lessons, and treat the students well… even when they don’t feel like it… they demonstrate their professionalism. And they earn the admiration of their colleagues.
