I learned what truly great leadership was at Microsoft in the mid-90s. My father passed away unexpectedly and I was devastated. My director at the time (who is now a VP), called me at my mother's home, and I was a mess. He told me how difficult it was to lose his own father and to take as much time as I needed to grieve. He told me not to worry about work and come back when I was ready. The call was short, maybe 2 minutes. I will never forget that call and its lesson. Empathy is the single greatest "skill" a leader can learn.
