Which characteristics do you admire the most in leaders?

For me, characteristics I admire the most in leaders are their confidence, and bravery maybe. By bravery I mean dealing constantly with everyone's needs and never ending new problems. When people around him are down and with no will to go forward, he is the one that brings them up and pushes them forward, providing hope and by his own example shows that nothing is impossible as long as they work hard for their dreams and for themselves.
