For example you will be more cautious when spending, as youve put your hard work and time to make that money, therefore you wont want to spend it all on one little item. Instead you will look out for sales and deals so you can stretch out your money as long as possible. This is important because, when you are older and in collage, or university you wont have much money and will need to be able to save as much as posable so you have enough money for meals everyday and personal items.
