I found this one particularly touching:
“Thank You. You’ve actually caught my interests in science, which I never felt smart enough for. You’re also one of the most understanding and empathetic professors I’ve had, which helped with my severe anxiety disorder.”
This is so important to me. Being able to touch people’s lives in a positive way . . . well, that’s why I’m doing this. It feels really good to know that, at least some of the time, I’m hitting the mark.
