We've met in a formal setting and I think I made a good impression on him. We've both been with the firm a short time. I sent him an email after we met saying I was happy to meet him, he responded with the same and told me to stop by whenever.
I've never had a mentor before and think he would be a terrific mentor for me, and I a terrific mentee for him.
What steps should I take that will give me the best chance of forming this formal mentor/mentee relationship?
