And I'm going to play harmonica

Always I've wanted play some musical instrument, but never I've can do it because I don't have patience and coordination.
My dad loves the cowboy flims, when they go across the desert in the night and play harmonica by a bonfire. He wanted to play harmonica, but he thought that he wasn't be able to play it and shows me the lovely sound of this instrument.
Now, I have an harmonica called Mia R. Monica and I love her sound... it's so sweet! I have a book which teaches me how I must play Mia R. Monica too, but I think that I need a teacher because is so difficult learn it by myself. And I don't have patience.
I don't want to be like the legends of blues (I'm in love with Sonny Boy Wlliamson's songs!) or Paul McCartney, I only want to feel the whistle of my harmonica going out of my mouth while someone sings a love and sad song... and my best friend plays the guitar and sings in a rock band and he wants that I play Mia R. Monica in his band...
I must practise, practise and practise... practise a lot. And I know if I want something, I can do it. I know I'll be able to play Mia R. Monica.
