And you have made me very welcome.

But in this career, you owe it to yourself to keep your eyes open for the chance to extend yourself, and that chance has come up.

That doesn't mean I'll ever forget the friends I've made here, though.

Thank you for 6 years of the best of everything.

I have enjoyed my work here.

I have had the opportunity to work with some great people, and I've had the chance to play a part in some interesting experiences.

We really worked hard to make a contribution and our efforts have made a difference.

I've done these things with so many terrific people it would take up an hour to name you all.

Everyone has been an inspiration, in good times and bad.

So I want to say 'thank you'.

I will miss you all, and I wish you every success.

I never find it easy to say goodbye.

People become a part of your life and are no longer acquaintances but friends.

But it is not goodbye – more of a farewell.

I will be keeping in touch when I can, and I'll be looking forward to hearing how you're all doing.

So now a chapter of my life is about to end, and a new one is about to begin.

I have a new challenge.

I'm facing it with a mixture of emotions: some anticipation, some excitement and, naturally, some apprehension.

I don't know yet how it will turn out, but I do know this – if my new colleagues are even half as good to work with as you are, I'll enjoy my new work very well.
