So I sent a thank you email to a professor who wrote me a reference letter. I updated her on the results of my applications. She replied back in a really nice email congratulating me and giving me some suggestions for my future career. I feel kind of rude ending our conversation this way, but at the same time, I also think it might be annoying for her to see another thank you email from me. If I do reply, I will most likely just say thank you again, this time for your kind words, and so on, which sound a bit repetitive. What would be an appropriate thing to do in this situation?
