Public Sector? Labour TD?
Public sector is too general an area so I can't say yes or no. "Labour TD?" No, I'd never be a TD; way too hard a job with long hours, little job security and loads of stress. That goes for TD's from every party.
I think I would have liked to be an architect. When I was in school my main interest was in art (I came very close to taking a place in Art College) and I ended up in engineering. Architecture, for me, is the best of both worlds.
