7 years of separation(s)

I was just thinking today about how 7 years seems to be a defining period for me going back a ways now.  I finished college in 1988 without much of an idea of what I wanted to do for a career.  7 years later, I finished law school in 1995 with a very clear idea (become a law professor).  7 years after that, I started teaching law here at the University of Iowa in 2002.  And 7 years have passed since then, and now I'm about to move on to teaching law at Lewis & Clark Law School in Oregon.  Pretty coincidental . . . .
