Since yours might seem like a downer (I do wonder about a cynic who thinks  it's "truly empty" to call a next generation to improve the world), I'll match yours with Woodie Allen's "speech to the graduates." 

"Today, as never before in history, mankind stands at a crossroads. One path leads to despair and utter hopelessness. The other, to total extinction. Let us pray we have the wisdom to  choose wisely." 

And, you don't disappoint---warning us yet again about "feelings."  

What IS it about feelings that bothers and threatens you so? Were you a heartbroken turned into a "Heartbreaker"? 

My grad speech would be "Feel More; Analyze Less." As Ted Hesburgh often told graduates, "love and laughter" are the keys. But I suspect you aren't a big fan of Fr. Ted's vision of Catholic higher education.
