You may find learners could be quite demanding and recently, I have had to deal with a student who has been quite resistant to the lesson that I was delivering. He said that it wasn't because of me as a teacher but because he wanted to move up.
I was very supportive and told him that he would need to improve his reading and writing ability and complemented him on his ability to communicate well. He lightened up a bit.
Be positive and extend this positive attitude to your learners. It goes a long way.
