Students learn from people they love
I used to do IT support for a whole building when I was a undergrad student. One of the professors once had a quote stuck on her door:"People may forget what you say. 
They may forget what you did, 
but people will never forget 
how you made them feel."I was a drop-out college student who attended that small, cheap public university in the middle of nowhere as a last resort because I ran out of options in my country. Studying there was nothing short of life-changing. Long story short, 11 years later, I just earned my doctorate degree not so long ago and working my dream job.By the way, after graduating from the small state school, I got accepted in a much larger research university that gave me a free ride. But it was that little school that I had to work my ass 20 hours a week for 4 years that feel I owe my big gratitude for. That little school was the one that gave me hope that I could change my life and had professors and faculties that went out of their way to help a no-name international student. The other day, I was offered an internship in a very good place. The international student office told me I couldn't accept it because of the laws or whatever. There came a professor whom I barely talked to. She was then the head of the business school - one of the departments I did IT support for. She offered to go with me to that office to argue with the director of the international office on behalf of me. And she did. And she won. I didn't have to say a word.I think it was how you make them feel that makes them remember what you did, not the other way around.
