As a left handed person I learned to write everything differently.

I cross the t's going the opposite way that this font recommends, and I write some numbers (like 4 and 7) with some strokes going the "wrong" way.

Most of the world (writing included) isn't designed for lefties. But sometimes doing things the "wrong" way works better when you're in the minority. I'm not sure if this font helps or hurts.
