I haven't been in all that long, I'm getting ready to start the 4th year of my first actual flying assignment, but I learned something pretty early on that I tell everyone. It's sort of become my motto: The Air Force was the absolute best that it ever will be on the day that you joined. I don't mean that as it's new and cool, I mean that in the fact that there will be dozens of changes, and none of them are good. I challenged a bunch of the guys in my squadron to come up with one good change that's happened to the Air Force since they joined, the only one anybody could come up with... now we can walk and talk on the phone at the same time. Seriously, think about it.
