If your in your 12-15 ages, start out with a local community job. Like maybe mowing lawns, baby sitting, leaf raking, etc. You might make a few hundred bucks on that. Other than that, get a job.
Another thing I forgot to mention is when you're about 15-18, a good job in the summer would be a local food market or restaurant. Waiting tables is a good way to start getting some money in the pocket.
i am a babysitter for my neighbors and they give me 10 bucks an hour. But if there is nobody young enough to babysit near u, i dontknow what to tell you
