Four years of schooling and a summer spent, mostly, planning. Ready or not, the students will come. I submitted my lesson plans yesterday. I have my to-do list for when I get to school. I feel prepared.
In the end, though, I need to take the advice of my colleague: "Go in, have fun. You can't take back the first day."
To any other new teachers, best of luck. Remember, we love this career!
