Right, the list of things I'll try to do

I always get at least £10 every week. Then I add:

£1 if I get to school before 8.45 every day
£1 if I eat reasonably healthily during the week (eg, eat loads of veg and no days where I eat nothing but toast and/or chocolate!)
£1 if I keep my room reasonable
£2 if I don't buy any unnecessary DVDs/CDs/books (but some have to be bought and I won't penalise myself for them)
50p for every time I initiate an unnecessary conversation with someone I don't know very well (e.g. teachers at school) up to a max of £5.

That's it for now, but if I do these things, I can get a max of £20 per week in the computer fund. More if I think of more things to add. I might have a new computer by the summer!

My computer plan

That's it, I'm getting a new computer. Sorry, my computer, but you're six years old now, and to be frank, you suck. So I need a new one. One that does what you want it to do and not five minutes after you tell it too. One that had the capacity to run Paintshop Pro without a sixty second or more delay on everything that you try to do. So I'm launching Operation Get-a-new-computer as of today. Technically, I probably can afford to get one today if I wanted too, bu that would completely wipe out my savings, especially considering that after years of this one I want the best I can get. So the plan is this - saving up. I'm going to put £10 a week in the computer fund, and add to that if I do/fail to do certain things. I'll make a list/ Like maybe I can add £2 if I keep my room reasonable, or if I eat relatively healthily, or if I apply for x many jobs. Whatever, the point is the better I do, the sooner I get a computer. Of course, it'll all go wrong within a week or two, but for now that's the plan.
