Broaden your search by looking at industry sectors not just the jobs within them. For example, it you're interested in nursing, think health care. Interested in computer programming? Think information technology.
Be careful where you get your intel. Many groups present information in a way that supports their own goals. This is true of organizations, businesses, political causes and lobby groups. Claims that sound too good to be true usually are.
Check the date of information you're using. Is it current? Information about jobs can go stale quickly. This is just as true about the future. We can't be sure what may happen years into the future. Information with those kind of predictions shouldn't form the core of your career plan. But it can give you some insight as you gather research.
Gather information from a number of sources. Compare what you find. Can you note biases? Use various sources to create a well-rounded perspective.
Look for information that applies to where you're living now or where you'd like to live. Some types of work are only available in specific locations. Examples would be jobs that are only in large urban centres or only in remote areas.
Do people keep talking about the same jobs, programs or businesses? Are you interested in this area of work? Are you looking in the right place for information? These patterns may be pointing you in promising directions.
