I’ve been reading a lot of Peter Drucker (and his ilk) lately. I particularly like his perspectives on knowledge workers. That’s essentially what we all are and I’m not totally convinced that it’s a good thing. I think the next generation will prefer to be considered maybe “knowledge craftsmen”. Anyway, here’s his definition:

Knowledge work can ultimately be judged on whether or not three things occur:

1) when something successful that never existed previously, is now up and running;

2) when something successful that existed previously has been improved or expanded; or

3) when something unsuccessful that existed previously has been stopped.
