If life is a classroom then you’re still in the learning process part. In the learning process part, if you make a mistake you can just erase it and try again. In a classroom your mistakes deserve course correction and education, not punishment. Here the goal is to teach you how to behave better, not to fail or get rid of you. In a classroom, you can be a work in progress, and that’s okay. In a classroom, you are free to make mistakes in order to learn, because mistakes are part of learning. There are still consequences to every choice, but in a classroom you can’t fail, because your value isn’t on the line. If life is a classroom, you have the same value no matter how much you struggle, how many mistakes you make or how you perform. If life is a classroom you are safe.
