You will find in teaching that the bar is constantly raised. I suspect that you doing well. The funny thing about teachers is that they forget that finding fault, criticising is actually very easy when you are sittimg at the back looking at someone. Being objective and remembering that it isn't just children that need praise as well as targets to improve. Trainee teachers, NQTs, middle managers and even senior managers need this as well.

I tell my trainees (and will do so when I see them on Friday) that they should look back at some of their early work/lessons and just see how far they have come from first being in the class teaching. Why don't you do this and reflect on your journey - where you started and what you are doing now that you couldn't have done last September.
