It is important to have fun in the opening moments of class, as the best instructors always helped us relax and prep for learning. I would like to focus on this since I have a pattern of starting with a greeting then covering the objectives for the class.

Prepare, prepare, prepare...and have key components listed that you know you want to cover, that are part of your list. I also make notes of things I've agreed to do for the students, as they ask for certain things in class, like changing the "due date and time" from 10pm to 11:59pm (23:59.)  

Observing others who have honed their skills, while always asking how I can improve my skills as an instructor. Being professional, leading by example, and keeping the focus on student learning acquisition rather than just focusing on my teaching abilities.
