Take Piano lessons. It's the only instrument that treats both hands equally. Also just do more stuff with your other hand. I think that "handedness" is a bunch of BS and that everyone can do anything with both hands if they just "practice" for decades, like we do with our one hand. Left handed people have no problem driving a stick shift because no one tells them they'll have a problem. Hmm. Tell them they can't write with the right hand and bingo, they can't, because they don't even try.
