If there's a better sub for specialized advice about education, please direct me there.
In order to be able to serve a broader range of customers and increase my value as an employee, I want to become fluent in Spanish and ASL. I don't want to pursue a degree. Is a college or university the best way to go, or should I try something else? I'm in the Charlotte area so any resources that aren't nearby, such as moving to Tijuana, are out of the question.
