①The idea that great progress is possible, whatever line of work you choose.

②There will always be cynics and critics on the sidelines tearing people down, and just as harmful are those people with good intentions who make no contribution at all.

③In his letter from the Birmingham jail, Dr. King wrote that our society needed to repent, not merely for the hateful words of the bad people, but for the appalling silence of the good people.

④The sidelines are not where you want to live your life.

⑤The world needs you in the arena. ⑥There are problems that need to be solved.

⑦Injustices that need to be ended. ⑧People that are still being persecuted, diseases still in need of cure.

⑨No matter what you do next, the world needs your energy, your passion, your impatience with progress.

⑩Don't shrink from risk. And tune out those critics and cynics.

?History rarely yields to one person, but think, and never forget, what happens when it does. ?That can be you. That should be you. That must be you.

?Congratulations Class of 2015. I'd like to take one photo of you, because this is the best view in the world. And it's a great one.
