I’m really happy and appreciate your genuine long lasting support on my work of accent reduction. John! It’s thanks to your help that these days I have got observable improvement in my English pronunciation. These days, thanks to your tips I could listen to CNN news at least 60% of it. RADICAL change to me. John, all I can say is Million Thanks!!!!!!
On this Christmas season, I’m enjoying my English listening to movies, news and songs as John’s Christmas Gift for me!
Again and again Many Thanks!
