I want to try

I'm thirty years old, and now I say said to myself stop! Now I want to improve (a lot... the street is long I think) my English.

The first reason is the work, I need to learn English for my job, for my future, but there is another reason...
I don't want more singing english song speaking kiwi melon, kiwi melon, na, na, na, looooove, mmmm, na, na, and other strange words :D

I tell you the true  truth... I feel a pinch of bashfulness because I know that I'm a goat in English but with your help I can do it... I think... I hope...
