Whether you're trying to pick a first or a second career O*NET OnLine, sponsored by the U.S. Department of Labor, may be just the tool you need:
It allows you to
browse descriptions of occupations based on your interests, skills,
abilities, and knowledge, as well as on the amount of preparation
needed. It also provides a list of jobs in the "Green Economy Sector."
Each occupational description includes information about tasks
performed, tools and technology used, knowledge, skills, and abilities
required, work activities, work context, and education needed. It's
often said that if you find a job you enjoy, you'll never have to "work"
a day in your life. Good luck with finding your own work-free job!
