Ask any career counselor: working in the wrong field is like trying to write with your less-dominant hand. Maybe you can struggle along, but you're never going to excel – and worst of all, it's uncomfortable. That's why the goal when picking a career isn't to choose the highest-paying job or even the job with the best occupational outlook. To really do well in your chosen field, you need to pick a job that fits your personality, skills, aptitudes, and interests. PayScale's latest data package helps you determine just that, starting with an interactive quiz that helps you figure out which job is the best job for you.
