I'm left handed and chose to learn to play right handed before I ever picked up a guitar. I am interested in mostly Blues, Rock, and some Metal. Any ideas or tips on increasing speed and accuracy with my right hand.

I'm still early in my learning, but eventually I would like to be able to build speed enough for some metal tunes. Am I asking too much out of my weaker hand, or is it just a matter of practice?

Any advice would be awesome!
