Carol,
I frequently tell new instructors they have the advantage of years of practical work experience. I believe this is the hook that can help motivate students because it's something they don't have, you do, and I find almost always students are interested in stories, situations, past work experiences (good and bad), and case studies that illuminate how best to (and not do) whatever skills are being taught. When students see you as the resident expert, respect, attention, trust, and seeking you for answers will be the likely result, and less frustration for you.
