A good leader sets a goal that is outside of our comfort zone and little by little works towards achieving those goals. Along the way, as steady progress is made, that once lofty goal starts to become more reasonable and others start to buy in. This seems to be the approach Elon has taken with Tesla and SpaceX. From personal experience I can tell you that simply making these lofty goals has attracted a lot of young, idealistic folk that are willing to put in a lot of sweat to show that this kind of stuff is within our reach.
