Not to be a cynic but why feel sorry? My wife and I racked up around £50k of student debt but were happy to do so as a calculated investment in our futures. Its a bit like putting up a new shed - if it wont pay then dont do it.
For ag students there is always good money to be made working over the summer.
For serious economy I would suggest:
1) Not buying a plasma TV and games machine.
2) Not drinking alcohol.
3) For Askham Brian students - not going out in York (or anywhere) of an evening.
4) Learn how to cook when you are young. Basic things like omlette take no time and cost almost nothing. Surely ag students must be able to get decent prices eggs etc?
5) Think about things you need like clothes and get them for Christmas or birthday.
6) Chances are you dont need a car.
7) Make a budget and stick to it. Make it realistic or you wont be able to stick to it in the first place. Make your budget around your needs and then figure out how to get the money, rather than work out how much you have got and then how much you can spend on an area.
8) Mobile phone? Why?
9) Help each other to save - have nights in, cook in a group, share the bills, have a car pool.
10) If you cant afford to go, save up and then go.
