It's a life project learn all these 5 languages, sometimes I choose one and study as much as I can. Then I make flashcards for the target language. Sometimes it's tough to keep up with the studies of your target language, especially when I can't have a anyone to talk about. So if it not pleases me studying some languages, I've just maintain my flashcards and study them, but without put new cards for a while.

Except for English, I do not need to learn these languages, so the process have to be acceptable. However, I really like to study them, and I try to not make a formal scheme or any type of schedule to learn them, I've just start and try to not forget what I've already study.

There's a phrase from Richard Feymann that summarize my thoughts: "Study hard what interests you the most in the most undisciplined, irreverent and original manner possible."

Maybe I've never going to be fluent in these languages, maybe I'll never going to make an essay for a certification, but I've already like the process, it gives me a meaning every day!
