The short answer is since this is a really difficult job market, you might as well try for something you enjoy, and if it is something you are good at, you will be able to convince potential employers and get a job. If you are really really good at something, you might even be able to make a lot of money, whatever this something is.
The long answer is the following. The first thing to do when picking a carrer is to make a list of everything you are good at doing and everything you are really bad at. Include not only academic skills (writing, math, science...) but also more general skills not necessarily valued at school (physical skills, art skills, communication skills, organizational skills, social skills, adaptation to diverse cultural settings, etc...). Then, make a list of the major branches of the job market that you would be willing to consider (health care, education, business, art, small crafts, travel, etc....). Next, match your skills to specific positions within each of these large categories. Last, decide which of these you think would make you the happiest to study and later on to work at/on. Take every opportunity to consult with people working these jobs to figure out what they do all day long, what the most enjoyable and the most unpleasant parts of their jobs are, and what the things most appreciated for an entry position are.
Good luck !!
