I Thought

I have just finished a conversation in English with my American friend, who I met here on Italki. It is not the first time I have spoken to  talk with him; step by step I am making improvements and correcting my pronunciation.
This My friend have has noticed my progress it and that makes me very happy and proud to continue with in my studies.
Afterwards I am angry with myself because I always underestimated the importance of English and of all languages.
I would like to return back of some of the years ago but I am going to keep studying it. This is what It is that I want!!!

A Thought

I've just finished a conversation in English with my American friend, whom I met here on Italki. It isn't the first time I've spoken with him; step by step (or, 'little by little' or 'slowly but surely') I'm making progress and correcting my pronunciation.

My friend has noticed this, which makes me very happy and proud to continue with my studies.

Afterwards I'm angry with myself because I always underestimated the importance of English and of other languages. I'd like to turn back the clock, but I'm going to keep studying it. This is what I want!

Well done, Gaetano - very few errors, and all minor! The 'troncamenti' that I've highlighted in yellow make the text sound more natural in informal text of this type. In formal text you'd maybe prefer to avoid the elision, but it sounds a little stilted to use 'I am' and 'I would' instead of 'I'm and I'd' in informal text such as this.
