Dear [recipient's name]:
Thank you so much for taking time out of your busy schedule to listen and provide me with advice on my career goals. What you said makes so much sense, and I am already implementing some of the tips you gave me. I will keep you informed on things and will let you know if I would like additional advice and guidance.
Thanks again for being there for me when I needed a listening ear and some words of wisdom. It means so much to me.
