Not everyone enjoys being the lifeguard whom everyone talks to, or the coffee shop barista who takes orders. Since those are two of the jobs that teens tend to gravitate toward, it might seem difficult at first to pin down some options for a quiet teenager. Think out of the box, though, and you'll find a job that best suits you -- one that may help you prepare for a promising career.

Website Work

Teens are often more adept at fixing computers and navigating websites than their parents or grandparents, and that's perfect for jobs that involve computer work. If you are a tech-savvy teen, you should have no problem creating websites for individuals and businesses, managing social networking sites for small companies, or training others how to use computers. You can set your own hours, and according to the Bureau of Labor Statistics, you don't necessarily need a degree to do the job -- especially if you are an enterprising teen who finds his own clients. The lowest 10 percent of Web developers earned a median income of $16.02 per hour as of 2013, according to BLS.

Library Assistant

Libraries are synonymous with quiet, so they can definitely be a place for a quiet teen to work. Library assistants don't need to have any specific training, and they tend to work typical 9-to-5 hours. In a smaller town or a place with many available jobs, the job of restocking shelves and organizing files could definitely go to a teen. The lowest 10 percent of library assistants earned a mean hourly wage of $8.27 as of 2013, according to BLS.

Making Deliveries

While you'll have to talk briefly with the people for whom you're making deliveries, doing this type of job is largely an independent one. You need to be 17 or older in order to make deliveries or do work-related tasks with a car. If you're 16 or under, however, you can still do a delivery job on foot, bicycle or via public transportation, according to the U.S. Department of Labor's Youth Rules website. The BLS doesn't differentiate between delivery workers who drive from those who don't, but the lowest 10 percent of workers earned a mean hourly wage of $13.41 as of May 2013.
