Yea, for someone with a background in French though, Spanish is the next most practical (and attainable) language to learn. Mandarin is nearly impossible to learn unless you have lots of time, patience, and practice (read: live in China for a few years). If you really want another language (one that you can learn in less than a year with lots of practice - which you would be able to get with native speakers in pretty much any American town), go with Spanish.
