What are you going to be when you grow up? That's the question that school age children ask all through their young years. New college students often begin and end their college stay with different majors and even those well past their college days change their career multiple times. If you're thinking about what your first or next job will be, there are a few that you might want to cross off your list of possibilities. These jobs have so few openings that landing a position in one of these professions is nearly statistically impossible.

You might enjoy your time refereeing amateur sporting events, but making it to the pros is going to be tough. There are only about 2,000 referees employed, making opportunities in this field slim.

Private Chef
Do you have dreams of cooking for celebrities? Private chefs often serve the ultra-wealthy which may include professional athletes, entertainers, CEOs and other financially successful individuals. Becoming a chef is well within your grasp, but the Bureau of Labor Statistics (BLS) forecasts only 180 openings for private chefs between 2006 and 2016. Roughly 980 private chefs are currently employed. If you do beat the odds, you're likely to make around $25,000 per year which is lower than other chefs that make an average of nearly $41,000.

Professional Athlete
If your gift is sports, you've likely heard that the odds of becoming a professional athlete are not in your favor. Unfortunately, those stories are correct. According to mathematical odds, you have a better chance of being hit by lightning than becoming a professional athlete. There are only about 9,400 professional athletes employed. Of course, the odds don't take into account those with exceptional abilities.

Forest Fire Inspector
A forest fire inspector may not be as high-profile as some jobs on our list, but if it's your passion it won't be easy to get a job. The Bureau of Labor Statistics says that there will only be a need for around 38 inspectors between 2006 and 2016. In 2011 over 1,500 people were employed as forest fire inspectors.

The Bottom Line
It may be difficult to find a position in one of these fields, but there are other fields that have plenty of openings. Many of these jobs pay salaries at or above some on our list. Software engineers, health care professionals and sale professionals are just a few of the careers with shortages.
