self-taught with poetry
A friend of mine is self-taught in spanish language.He loves Frederico Garcia Lorca and generally the Spanish history so he decided to learn.He can speak clearly and understand everything after 5 years.Do you think that i can do the same with french?I mean by translating poems and songs(of course continue my lessons for grammar and vocabulary). Which poets or writers would you suggest?
I'm not sure if poetry is a good idea if you want to communicate. I'd rather think of books that include dialogs, and that were written rather recently. Otherwise you will sound like Molière ;-) (Which is not bad at all, it may only come as a surprise to the people you will be talking to... )
I like "35 kilos d'espoir" by Anna Gavalda. https://www.amazon.com/35-kilos-d%C2%B4espoir-Anna-Gavalda/dp/3150091489 It's written in quite easy language, I feel, and it includes many dialogs.
The classic: "Le petit prince" by Antoine de Saint-Exupéry: https://www.amazon.com/Petit-Prince-French-Language/dp/0156013983/ref=sr_1_1?s=booksie=UTF8qid=1522442821sr=1-1keywords=le+petit+princedpID=51364NhwLoLpreST=_SY291_BO1,204,203,200_QL40_dpSrc=srch It's a little older, of course, but very poetic and lovely.
And I'm a great fan of Boris Vian. https://en.wikipedia.org/wiki/Boris_Vian But his poems and stories are really difficult to understand (but very, very cool).
It's about a boy, but I don't think the book is for children (alone). But if you like to be challenged, then Boris Vian is your best bet. (I guess that nowadays, you will find a lot of explanation online. When I read his texts (in particular "Trouble dans les Andains"), there was no such thing as the Internet .....)
