Add a second language and boost career

Most Americans took a couple of years worth of credits in a secondary language class in high school or college, but according to the Library of Economics and Liberty as few as .7 percent, or less than one student in 100, actually achieved fluency.

But fluency in a second language can be profitable.

According to U.S. News, new members to the workforce in 2014 could expect an additional 10 to 15 percent pay increase if they were fluent in a second language.  Language fluency can be essential for businesses with a global presence. As an example, many American firms outsource their manufacturing to places like China in order to maintain competitive prices. Having people fluent in both English and Chinese is essential up and down the product and command chains.

According to Forbes, language skills can help employees stay relevant in a current position, switch jobs, or launch a new career altogether.

Today, for maximum effectiveness, try Mandarin-Chinese, German, and Spanish as good picks for a second languages.

Although children learn new languages most easily, adults can do it as well through a process of formal study, daily practice, and engaging in immersion activities.

For those looking to dabble before making a big financial commitment, there are many free online resources and sophisticated smartphone apps to get started.
