Learn to Speak A New Language

English is my first language. In fact, it is my only language. I understand some French, and my Greek is laughable, even after living there for more than a year. I studied French in school, but it's weak, at best. I would like to learn to speak at least one new language fluently...perhaps I will select one of these languages, on which I have some sort of handle, but there are many that I want to master. Spanish, Russian, and Italian are contenders, as are a number of Asian languages.
