It really depends. You're too young to be hired by any company. There are labor laws.
But, if your parents agree, you can babysit, you can walk dogs, you can shovel snow, you can mow lawns, you can get a paper route.
It's great that you want to earn money, and I fully support that, but do keep in mind that your main responsibility right now is to do well in school. You see, school is a stepping stone. Do well in school, go to college, and then you can get a job that's a lot better than a paper route. If your job has a negative effect on your school work, then you're really shooting yourself in the foot.
Good luck, and don't worry, you'll be allowed to work very soon, and you'll be working for a very long time after that. In fact, you have the rest of your life to work.
