Interesting question.
I found lots of leaders in the military that I thought were "like me". That is to say relatively smart, motivated folks that worked very hard, tried to do the right thing and were totally trustworthy. Maybe that is self-congratulatory, I don't know.
There were also quite a few extrordinarly poor leaders I had to serve with and there were a very few of those born leaders that I would have followed anywhere. While I always ranked highly in my military training and evaluations, there were always many in my peer group that I looked up to as great leaders.
I would say the things I learned about myself were just as important as most of the skills or attitudes I developed/refined in the military. The concept of "Be, Know, Do" has stuck with me for life.
In the corporate world, there have been a rare few peers that I felt "outclassed" me in terms of skill.
As far us higher level leaders, I've unfortunately, never had the pleasure of working for anyone that I could really look up to, or would want a mentoring type relationship with. Not that they are not out there, I've just been unlucky. Anytime I got on a team where I felt I could really respect a particular manager another re-org would come along and I'd be working for a dipstick again.
As a wet behind the ears 2LT, I had mentor relationships with both the S4 (O3) and the Deputy BN XO (04), both of these guys were Vietnam combat vets and their influnce was very important for me since my 1st CO was an a$$clown.
He was an AG Officer and thought he was the shiznit. I came to him right after completing IOBC (on the Commandant's list) and Airborne. I couldn't really get into his "highspeed" low drag BS,with his being AG and all.
Anyway the relationships with those higher level officers were crucial in getting me off on the right foot.
I do have to say that I miss being able to simply give a directive and expect it to be carried out professionally and without discussion. Everything has to be so touchy feely these days.
