I watch this every year several times before and after school starts. I still get a bit nervous walking into a classroom with dozens of eyes staring at me. It is a bit nerve-wracking knowing that I can change what a child thinks about learning. I can help them see how fun and life changing it is, or I can turn them off of it forever.
So, knowing that I can influence so many children every year just by teaching, is scary. But I love doing it and wouldn't want any other job in the world.
Most people have probably seen this, but if you haven't watch it. It will get you pumped to walk into your classroom.
