I agree. I don't find satisfaction in being told I'm a nice instructor because I am also a good instructor.
A good instructor does not do her job only for the paycheck. She is passionate about teaching and compassionate with her students. She herself coould not stop learning and improving so she gets better in her profession. I'd say I am both good and nice, but I prefer that my students like me for the right reason--they learn from me and I make a difference in their lives.
