Left-handers have it hard enough in this right-handed world and should be encouraged to do whatever they find comfortable, IMO. Thinking about it...I've heard that same encouragement about guitar playing.
On the other hand, three of the four last Presidents are left-handed...just sayin'. ;)
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
