How long does is usually take to learn a Romance language?

Well not everyone is the same so everyone learns a language at their own pace. The same with the languages you're learning, some people may find French & Italian hard to learn though while others may find it easier & learn it faster. A person that already speaks a romance language for example, will find it easier to learn any other romance language since they're actually quite similar. I've heard that you don't exactly fully master a language until about 7years studying it, but I wouldn't be too sure about that...
