Being a substitute teacher

I was just done with one substitute class last night-- Grammar for Intermediate Level. Though currently I am not a regular teacher for this kind, I was still pleased to be there. I have got lots of thinking about what I should do to improve my teaching skills next time for this level. Unfortunately last night during the class I was unable to go through all the things in my handouts, but Julie told me that it is normal for a substitute teacher who cannot cover everything before the class wraps up since there is too much stuff in the textbook. On hearing that, I felt much more assured. Things can get better, so I will cross my fingers for myself.
