I spent my childhood clad in 1970s hand-me-downs, primarily from male cousins, which mainly consisted of a selection of beige, brown and orange dungarees. That, combined with a perfectly round pudding-bowl haircut, made me look, on a good day, like a cross between Ann Widdecombe, one of the Flower Pot Men, and a monk.
While you're going through this process of trying to find the satisfaction in your work, pretend you feel satisfied. Tell yourself you had a good day. Walk through the corridors with a smile rather than a scowl. Your positive energy will radiate. If you act like you're having fun, you'll find you are having fun.
