I actually have played with the handwriting/personality a fair amount, and find what font i write in changes how i think.
block/architect letters: serious, note-taking. slower and more deliberate
elementary lower-case printing: shopping lists, casual notes
cursive - letters to self, observations, consciously writing
it's not scientific or anything, but i've found myself writing far more profoundly when i'm being conscious of the evenness aesthetically when it's coming out of my pen... makes the whole process flow better for me.
i have a fairly aware eye, so it's pretty easy for me to pick up on styles of handwriting. also, taking notes in college gives you plenty of practice when you want to develop a new one.
i wish learning new languages was as easy
