This is picked up at Powerline which is from a newly published book of Commencement Addresses by Conservatives. The one that Scott Johnson has reprinted is one given in 2008 by Justice Clarence Thomas. It really is worth your time, but I have selected this passage because it has its own meaning to me:

Take a few minutes today to say thank you to anyone who helped you get here. Then try to live your lives as if you really appreciate their help and the good it has done in your lives. Earn the right to have been helped by the way you live your lives.

Next, remember that life is not easy for any of us. It will probably not be fair, and it certainly is not all about you. The gray hair and wrinkles you see on older people have been earned the hard way, by living and dealing with the challenges of life. When I was a young adult and labored under the delusion of my own omniscience, I thought I knew more than I actually did. That is a function of youth.

With the wisdom that only comes with the passage of years, the older folks warned me presciently and ominously, “Son, you just live long enough and you’ll see.” They were right; oh, so right. Life is humbling and can be hard, very hard. It is a series of decisions, some harder than others, some good and, unfortunately, too many of them bad. It will be up to each of you to make as many good decisions as possible and to limit the bad ones, then to learn from all of them. But I will urge you to resist when those around you insist on making the bad decisions. Being accepted or popular with those doing wrong is an awful Faustian bargain and, as with all Faustian bargains, not worth it. It is never wrong to do the right thing. It may be hard, but never wrong.
