What kind of leaders do you admire most?

I am a leader, very intelligent, insightful, quick-thinking, and eloquent. I am a wandering crane in my life, meticulous in my work and extremely efficient. I often feel that he doesn't need our assistants, and he can do all the work by himself. The same is true. He used to have no assistant and did all the work by himself. In his words, he asked us to be assistants, giving us a chance.
