Original text - Spanish - Te he escrito esta carta porque quiero que sepas...

I'm writing you this postcard, because I would like you to know that you are my hero for the last six years from all angles, as a referee and as a person as well.
For me there is nobody like you, I think you're someone I can trust.
I would like to give you thanks for being like that, and to tell you not to change ever.
If it isn't too much to ask, I would like you to do me a favor, I'd appreciate so much that you send me, in Spain, a picture or a poster, exclusively dedicated to me, on which I could read something like : "To my friend Javi"

I won't do it myself, pluiepoco,but I'm not sure of my English, it's not my mother-tongue...

I will not do it again.

Sorry,

experts please correct me or re-translate perfectly.
