I suggest you move somewhere a little cheaper that falls in line with your current salary....whether your being paid enough or not. The main thing here is do not live beyond your means. People living just by gatwick...who have a bus laid on can fully afford accomodation. You are choosing to the live in the 3rd most expensive city in the world.
greigok, whilst you won't win many friends on here for saying that, I have to agree with you. Everyone has to live within their means, whether cabin crew or shop assistant; and their are plenty of people earning less than crew who seem to be able to manage.
Perhaps it's because their is an attitude that a glamourous job ought to come with a glamourous social life?
