Finally tonight, as promised, one of our favorite annual traditions around here, our salute to the graduates, inspiring words of wisdom for the class of 2016 from some folks we think youll recognize. Graduates, you are about to enter the most uncertain and thrilling period of your lives. The stories you are about to live are the ones youll be telling your children and grandchildren and therapists. Some of you have always known what you were born to do. Others are still trying to figure it out. And thats okay. Thats cool. Every stumble is not a fall. And every fall does not mean failure. Being human means youll make mistakes. Dont get too down on yourself. You have, you may not know them, hidden talents, skills, passions. You simply cannot recognize it yet. So listen to the wind, the answer might be blowing right past. Give yourself permission to take the time to figure out who you really are. And what you really want. The easy days ahead of you will be easy. The days that challenge you to your very core that will determine who you are. You will be defined not just by what you achieve, but by how you survive. Dont lose hope. If sometimes you hit a roadblock. Dont lose hope in the face of naysayers. As a friend of mine who happens to be from new jersey, a guy named Bruce Springsteen once sang, they spend their lives waiting for a moment that just dont come. Dont let that be you. I hope that all of you, whatever you choose to do in life, as graduates, will find ways to find each other and stay together. Do not forget the people who helped you. Forget the people who helped you. Now, to the parents who are here, moms and dads, if you feel anything like i did when my daughters graduated, your emotions have to be mixed. A little bit sad, a little bit relieved, incredibly proud, and absolutely blown away by how short the interval is between diapers and diplomas. As an educated person, you have an opportunity to spend your life doing what you love to do. And you should never forget that many people dont have that opportunity. Its time to move your tassel. Just be yourself, and if you cant be movie meet me in st. Louis. My god, she got to wear such cute outfits in that movie. The great philosopher and poet, mr. P. R. Nelson, once said, dearly beloved, we gather here today to get to this thing called life. We are the class of 2016 class of 2016 congratulations indeed to the class of 2016.
