Is there Twitter after retirement?

Of course, the Big Question is usually is there life after death?  But we can't answer that one here.  The lesser question - Is there Twitter after retirement? - can be answered, at least in the case of former UC prez Mark Yudof.  YES!  Not surprisingly, Yudof stopped tweeting around the time he left the UC presidency.  But then, in late December, came another tweet.  It's actually a link to a Harvard Business Review piece, and says:

"Once you know your greater purpose, there are lots of roads that will take you there." http://s.hbr.org/18NiGul

[See https://twitter.com/mark_yudof]

I always thought the quote was "if you don't know where you're going, any road'll take you there," a paraphrase from Alice in Wonderland.  In short, I couldn't make much sense of what the link was all about.  But what do I know?

Anyway, we await future rockin' links and tweets:
