*nods* agrees with the others.... realistically.
=Unrealistic THEORY=
-You can go grab some rich kid's wallet(Oh no, just kidding. Don't ever do this to anyone or at home)
-Make a debt and pay it with your body(i.e. slave, maid etc. nope, not what you are imagining

)
-Ask your parents to give you a bigger allowance(this was quite effective to me, i promised something like, I'm gonna eat vegetable now...)
-The one you want to buy, ask it to be your b-day present.
-Pawn anything valuable in your house
....anways 2 of the unrealistic suggestions are true and the other 3 were false. Ignore those suggestions XD
Well, I was once like you as well, "I will save my allowance and buy a psp!" my monthly allowance was 3500, but i was tempted to buy this and that or eat those or these and i ended up with nothing.

I still have been able to buy it, when i begged my mom that I'd eat all kinds of food, from fish to vegetables from yogurt to ampalaya juice. And I got my wish.
Anyways, the best way you can earn was indeed to work. But if you are still a student the only chance you can get is during summer or by selling stuff etc.(My friends and i once bargained used stuff and we actually earn a lot). Anyways, I was being off topic -_-
The only way i can tell you to save money is by: bringing your own food, water, whatever. And use as little possible money as you can if you can. If your home is not really far to your school, you could try to just walk, if its a bit far, you can walk or ride a bicycle... if its really far, you should spend a bit of your money or wake up early and ride your bicycle or walk(a good diet too)...---Well, this is a spartan way of saving money= killing yourself from hunger and tireness just to save money. :\
I haven't really saved up any money yet since, i was a spoiled brat who would get what she want with a
