I have been practicing a lot and i´m starting to see results now. I won´t definitely quit, you are all right, it is a strugle but there isn´t other way to success. This is a hard but lovely instrument and it really worth the effort. Thank you all very much for you support, i really apreciate it. Bye. Alan from Argentina.
