We have to be willing to grow both personally and professionally as an instructor. Being able to take constructive criticism and learn not only from your peers but from your students. You are not there JUST to teach them but to learn as well. Professional development is ongoing if you want to continue to strengthen those weak areas and you have to be open to it. No, we do not know everything and yes there is always someone smarter than you BUT its how you take it process it digest it and use it. Just because someone may know more than you does not make you any less of a person it means you have some more developing to do. We all have areas that need improvement! I think one of the biggest things i have learned being an instructor is to BE YOURSELF and TRUTHFUL. There is a certain standard (model) that we have to deliver in order to shape and mold our future students. It takes too much time and energy trying to be something you are not and students will see that very quickly and call you out. Communication is extremely important. We all communicate but to communicate EFFECTIVELY is worth a thousand words by decreasing anxiety, increasing trust and improving understanding among your students.
