Go to your neighbors, explain that you are looking to earn some money, and see if they need any odd jobs done, such as painting, or hauling things away from a garage.
I say follow that Star girls advice, you can do shore jobs for other people in your block.I used to do that when I was young and it was quick cash. Is pretty good for you.I m sure you get allowances and if you know your neighborhood very well or area, talk to the people around and let em know. Is a nice lil job on the side for the meantime.
as you are young to do job,you should be honest ask for your self why you need this? for what purpose your going to spend this money and ask your parents DO NOT STEAL its bad
