Probably unusually, I have to say that my 18 years here have not been - on balance - boring. A company of 300 or so is pretty good for moving quickly into new technologies, being the test-bed for the "bigger" company and generally having better opportunities to climb the ladder.
In passing, I would mention that a half decent Grammar School education probably helped, as you become "known" to the big bods pretty quickly when you can converse (be it via e-mail, or simply in conversation) in a manner that sets you apart.
I have been lucky. In fact, very lucky. I will miss the place terribly, but it is now time to move on and although nervous, I am also quite excited. Time to do what I want to do, rather than what is the safe option and pays the bills.
