I go through life feeling like a fraud. When I was at university I kept expecting someone to come up to me and say 'Hey you, you're not clever enough to be here! Who do you think you're kidding? Get out!' I get the same thing at work. I keep expecting my bosses to realise that I am actually stupid and rubbish and don't know what I'm doing, and then sack me. I am constantly slightly surprised when this doesn't happen.
