I have recently changed industries in my management career. I have an acquaintance whom is a CEO at a “competing” company of ours. He has agreed to meet with me for lunch later this week and basically mentor me in this industry and would like to create an alliance of sorts. My question is what would be an appropriate way of saying thank you in this type of situation. Also would it be appropriate to create a mentoring relationship with a person in the same industry as I work in. Any advice would be very much appreciated.
