I've been writing the same since Elementary. I write super small and in italics and the only thing that has changed over the years are my "A", "B", "D" and "2"'s.
I always write my name in cursive and everything else the normal way I write.
I have pretty good handwriting. I've always been complimented on it (if you consider people saying it looks 'girly' a compliment). However, when I'm taking notes or just randomly writing nonsense, I tend to go into a different style that is more italic-like, cursive-like, angled, and sloppy. At its worst, it's illegible. So, I go from one extreme to another.
