regarding mission statements

There is, of course, this -- which leads me to believe the previously mentioned reading list is still fairly relevant:

"Some of the most rewarding experiences we have come about through random circumstances of which we have no real understanding. It is sometimes important to commit to something we know very little about if the act of commitment in itself becomes part of an experience."
