An italian friend! :) (please correct me)

Hello everyone! My name is Antonio, an Italian native who lives and works in his country. About three years ago, my best friend moved to London (U.K.), where he has found a house and a job; from that moment on, I have travelled (1) to the (2) U.K. once per year, at least. These trips have helped me to discover how beautiful learning an international language is (3)! My motivation took flight when a French guy asked me some information (4) in his native language, but I wasn't able to help him, 'cause I don't speak French: after he thanked me, he found an English native speaker close to me, so he suddenly changed his way of speaking very fluently (5) to solve his problem... in a way that impressed me so much! In that moment, I promised to myself: "I WILL LEARN ENGLISH AS A SECOND LANGUAGE". However, I love my native language just as much same as me: in fact, I studied modern Italian literature at university and I have written (6) a lot of poems! For all these reasons, feel free to contact me for an advantageous language exchange! Ciao a tutti! :)

(1) Present perfect, because something that started in the past and it's still true now.  If you hadn't mentioned when it started, the presnt simple would be fine. (Something like: "I travel to London at least once a year to visit my best friend.")  

(2) Weird-exception countries we use 'the' for: the UK, the USA, the Czech Republic, the UAE. 

(3) Putting the verb before the subject is question word order.

(4) 'Information' is uncountable.

(5) In this order, 'fluently' sounds like it describes the change, rather than the speaking.  If I'm right and you mean his speaking became fluent, put something at the end like: "He spoke English very fluently."  If I'm wrong and you did mean the change was fluent, I think it would be less confusing to use 'smoothly' or 'easily'. :)

(6) You started writing in the past, you're still doing it, and you will do it some more in the future. =D
