"Learn" a second language
You don't need a second language to be a pilot. English is the required language for commercial flying. That said, it is great fun to speak a second language at street level. Forget 5 year courses. Go and live abroad, get a job stacking supermarket shelves and immerse yourself in local life. Even better, get a job washing down aircraft at a flying school. Six months and you'll be almost a native.
