The Guardian's 'Work' section on Saturday has a careers Agony Uncle you can write to. If that sounds a bit long-winded, I would suggest listing what you like, what you don't like, what you are good at, what you are bad at etc and seeing what broad conclusion you can reach. It is also worth remembering that 'having the best job in the world' is a pretty recent ambition and that pretending you have to love - as opposed to like/tolerate - your job is a 'must have' only in the realms of Sunday supplements and glossy, high-end women's/men's mags. I don't mean you shouldn't strive to do something that's right for you, but don't fall into the slavish trap of having to have it all, including a wonderful, enriching, soul-enhancing career.
