I have never been good at managing my finances, and living in London has definitely taught me the hard way that it is important to know when to spend and when to save. If you're like me and spend as soon as you've earned - even if you have never had a lot of money go into your account in one go - it is REALLY important to not go too crazy too soon. Take advantage of subsidised facilities - such as the local college, which is an excellent place to get a cheap haircut that is professionally observed - and make the most of all free opportunities at uni: you will never get it so cheap. The shopping scene in Kingston is fantastic but don't feel like you have to play a leading role, knowing the difference between a 'need' and a 'want' is invaluable. Trust me, I have had to spend a week eating 25p tins of baked beans just because I overdid it. You do not want to get to THAT stage.
