I play right-handed because I do favor the right hand, but have some facility with my left, as well. In baseball I was a switch hitter when I felt I could take advantage of it. I can do many other things with both hands like writing with both simultaneously. However, I have a left handed younger brother who plays in the right handed way. I know he struggled for years with it because his right hand was not very coordinated with rhythym and motion. However, he kept at it and got better. For many years now he has been a full-time guitar teacher. I did not encourage him one way or the other. I think he chose the right handed method because of the guitar he had and the chord books. I think he would have learned faster had he bought a left handed guitar and learned that way, since he struggled so much with it.

Ultimately, I find left-handed people very sinister!
