I think it is rewarding. My former T didn't get to experience the exponential growth I've experienced in this past year or so but she was with me for 10 years, walking through the hard times with me. So now when I tell her how well I'm doing, she is pleased and proud. Likewise my T that I have now seems very proud of me for how far I have come since I started with her and she always tells me now, "You are doing so good." It's like they are happy for me. If something good happens to a friend or a colleague I am happy for them, but I think it is deeper than that for the T because they helped me get there.
