Just because you're not the most outgoing person in the world doesn't mean you can't nab a great-paying gig. According to Business Insider, there are actually a number of careers that are very well suited to people who like working alone. Most of them are in the science, computer, and engineering fields. These positions usually require advanced degrees, but they tend to pay for themselves quickly, with starting salaries in the high $80,000 to $100,000 a year range.
