But all my hard work has paid off. I can now write comfortably with my non-dominant hand, and legibly as well! At my current level of muscle memory, I can write with my left hand just as quickly with my right with only moderate legibility issues. But if I slow down to about 75% of my right hand's speed, I can make my left handwriting nearly indistinguishable from that of my right. Behold the fruits of my labor:

What you're looking at is one line written by my dominant right hand, and the following four written with my left. It may not look like much improvement compared with that of my first post, but there is a marked increase in the speed with which I can write. As an added bonus, I discovered that I can write with both hands at the same time... which gets trippy when your hands move together most of the time, but cross t's and f's in opposite directions. My brain asplode!
