When it comes to solving really hard problems, Ma has a famous quote that I love: "Today is hard. Tomorrow will be worse. But the day after that will be beautiful. Most of your talent won't make it past tomorrow." But as a leader, you must inspire people through those hardest times: To stick with it, to move through it, and to see past it so they can make it to the day where things are beautiful. That's when you're really innovating. You have get your team there.
