God made everyone right-handed, the truly gifted overcome it.
The left-handed are precious; they take places which are inconvenient for the rest. Victor Hugo
If the left half of the brain controls the right half of the body then only left handed people are in the right mind. ~W.C. Fields
Left-handers are wired into the artistic half of the brain, which makes them imaginative, creative, surprising, ambiguous, exasperating, stubborn, emotional, witty, obsessive, infuriating, delightful, original, but never, never, dull. ~James T deKay
Edit: As for myself, I find that I seem to be more capable using either hand than most of the people around me. Also, I learned to play guitar right-handed because I taught myself by watching and listening to other players. All the ones I watched, played right-handed.
