Standing outside this iconic building I realised it is thirteen years since I worked here. So much has changed since then, and I don't just mean a new tube station.
I couldn't have guessed my next visit would be part of a programme designed to help those who are leaving. I'm attending a workshop called "setting up as a sole trader".
I remember my first course here in July 1983 as if it was yesterday.
Today feels exciting, scary and after twenty five years, rather momentous.
