“If things are ever to move upward, some one must take the first step, and assume the risk of it. No one who is not willing to try charity, to try non-resistance as the saint is always willing, can tell whether these methods will or will not succeed.”

2015, Young African Leaders Initiative Presidential Summit Town Hall speech (August 2015)
Context: And the one thing I’ve learned, both in my personal life and in my political life, is that if you want more authority, then you also have to be more responsible. You can’t wear the crown if you can’t bear the cross. […] So my attitude is, if you want to participate then you have to recognize that you have broader responsibilities. […] And that is part of leadership. That’s true, by the way, for you individually as well. You have to be willing to take some risks and do some hard things in order to be a leader. A leader is not just a name, a title, and privileges and perks.
