You are 21 years old and have just agreed to take a leap of faith and do this thing and teach. You know all too well just how little you know. You are going into this blind even if you are aware of your lack of sight.
At every point in this process, you are going to believe that this must be the hardest part. Passing the Praxis, surviving the first week of school, planning for three preps, balancing teaching and coaching and a life of your own, teaching 150 kids in the poorest corner of the poorest state in the country and finding something to love in each and every one of them. At every point in this process, you will be wrong. None of these tasks is the hardest part.
The hardest part starts the moment you agree to do this and will stay with you years after you leave teaching. It stares you in the mirror every morning when you wake and again at night before you lay your head down to sleep. Nearly two years in, you have not even begun to master it, though, you know it is the only thing that will allow you to survive in this job. Here is the hardest part, the skill no one tells you you must have in order to teach: Forgiveness. You must learn to forgive yourself.
Forgive yourself because you have no idea what to do. You will stumble through lessons on topics you are not quite qualified to teach. You will write a kid up when they don't deserve it and not write them up when they most certainly do. You will realize two days into a unit that you have taught an entire skill wrong. You will write tests that are too hard, too easy, and never quite find the right spot in between. Forgive yourself. You are doing the best that you know how to do.
Forgive yourself because you will make every mistake in the book and then write a few new pages of your own. For most of the first half of the first year, you are going to do more things wrong than you do right. You will regret words as soon as you have said them and more than that you will regret the words you do not say at all. Forgive yourself. You are doing the best that you know how to do.
Forgive yourself because even after you have learned how to do better and be the teacher your students deserve, you will not always be allowed to do it. You will be forced again and again to make decisions that you know are wrong for your students. You are working within a system that is stacked against you and your students. You will give test after test after test and know the whole time that it is wrong. You will postpone learning for the sake of "education" and again you will know that it is wrong. When you can you will fight it, but too often you cannot. Forgive yourself. You are doing the best that you know how to do.
Forgive yourself because your students are slipping through your fingers. You will always be running out of time in the class period, in the marking period, in the year. Your time will run out and you will wonder if they have learned anything at all. Forgive yourself. You are doing the best that you know how to do.
Forgive yourself because even if you are the perfect teacher it will not be enough. You will lose some of your students to all manner of misfortune, to jail, to the streets, to time. Rational expressions and binder grades and performance tasks will not stop a speeding bullet when it comes for one of your students. Forgive yourself. You are doing the best that you know how to do.
