Instead, have it in mind that you are going to TEACH people something.
That means that what you say is directed at them, not at the lesson plan. It means that your pace is leisurely, with plenty of pauses to let students reflect for a moment on what you have just said.
Keep the students uppermost in your mind. A successful lesson is one in which they feel "improved" -- not one where the teacher has managed to race through every word in a lesson plan. The class is not about you and it is CERTAINLY not about the lesson plan. It is only about the students.
If you have ended up making them be able to do something they could never do before, that is a successful lesson.
I can't imagine that one 40-minute period, with ample time for the students to interact with the material, could ever use even half of your planned lesson.
I think you have so much material planned that you will get in trouble by trying to fit it all in.
One thing you can do is to be aware of all the small places in your plan that would serve as natural stopping places if you run out of time. Then, when you see that you have only a few minutes left, you can bring the lesson to a graceful close no matter where you are on your plan.
Try to have fun in class and try to enjoy being with the students. Forget about yourself. Just think about only this: You are there to sincerely work with others for their benefit, to show them something they want to know.
