In August of last year, I enrolled for French classes. Initially I thought I'd complete the first level and be done with it, but it is now May and I'm nearly done with my third level. Not only is it extremely interesting to understand the nuances of a different language, it also helps you get a glimpse into the culture and look beyond social stereotypes.
The secret to learning a new language isn't much of a secret at all. It is difficult because we think in the language we're most fluent in and choose to directly translate. Also, it's frustrating when all you can manage are elementary sentences and feel like you cannot be yourself in a different language. But, if you stick with, you'll be multi-lingual, a skill that would definitely aid you in your professional and personal life.
