Get Your Students Hired
I completely agree it is important to begin a class lecture with a statement intent on getting the student's attention is an interesting concept and one I will use over and over again.
I usually come in pleasant and happy I try my best to make them realize your future is what you make of it. What has motivated you today. First you are an American getting a good education , think of health, etc. I try to knotg out any negative speech. Inspire, motivate and appreciate.
