I'm with Ripsnort on moving from job to job...
I've been with the same organization for the past 12 years, but I've changed jobs four times. Funny thing is... as soon as I'm there long enough to get comfortable, I get bored with it. The downside is that the new jobs are becoming more and more uncomfortable at the start. I keep wondering when I'm going to become proof of the "peter principle."
