When kids are told they can grow up to be whatever they want, they tend to dream big. According to a recent survey by TollFreeForwarding, high-paying and glamorous job titles like doctor, actor, and pro sports star are some of the most common childhood dream careers in America. But the same survey also found that just a small fraction of people go on to become what they wanted to be when they were young.

The virtual phone company surveyed 2000 adults in the U.S., asking them what career they dreamed of pursuing when they were teenagers. Public service jobs proved the most popular, with teacher, doctor/nurse, and vet making up the top three spots on the list. Those were followed by musician, actor, pro sports, and writer—all jobs that many kids associate with celebrities. Scientist, lawyer, and artist rounded out the top 10. (You can see the whole breakdown here.)

Of the people surveyed, only 10 percent reported holding their dream job today. The most common reasons they gave for not achieving their childhood dreams were financial limitations, a lack of skills, and prioritizing family. Only 39 percent of people who never landed their dream job said they regretted it.

That 10 percent may seem small, but TollFreeForwarding also found that an additional 14 percent of respondents had held their former dream job at some point in their lives, even if they don't have that job today. And dream jobs aren't always all they're made out to be—among the people surveyed who achieved their childhood dream, just 64 percent said it met their childhood expectations.

If you're still set on pursuing your dream job in light of these facts, there is a right way to go about it. Here are some tips for making your most ambitious career goals come true.
